Najm al-Din al-Katibi's al-Risalah al-Shamsiyyah is a scholarly edition and translation of The Canons of Logic, with additional commentary and notes. Composed by Najm al-Din al-Katibi, a scholar of the Shafi'i school of law, al-Risalah al-Shamsiyyah is the most widely read introduction to logic in the Arabic-speaking world. It has probably enjoyed a longer shelf-life than any other logic textbook ever written, having been in use by madrasa students from the early fourteenth century up until the present day. Building on (...) the theories of Avicenna, al-Razi, and other pioneers of logic, al-Katibi discusses the many pitfalls of building arguments and setting out unambiguous claims in natural language. The enduring nature of the text is a testament to al-Katibi and his impact on concepts of formal discourse and argument. (shrink)

Logic was revered in the thirteenth century, perhaps more highly than it has been revered before or since. In the Muslim East, logic was an integral part of the syllabus of schools and found to be especially helpful for legal studies. It was at this time that The Canons of Logic was composed by Najm al-Din al-Katibi, a scholar of the Shafi'i school of law. The Rules of Logic is the most widely read introduction to logic in the Arabic-speaking world. (...) It has probably enjoyed a longer shelf-life than any other logic textbook ever written, having been in use by madrasa students from the early fourteenth century up until the present day. Building on the theories of Avicenna, al-Razi, and other pioneers of logic, al-Katibi discusses the many pitfalls of building arguments and setting out unambiguous claims in natural language. The enduring nature of the text is a testament to al-Katibi and his impact on concepts of formal discourse and argument. This new translation of The Canons of Logic provides new life to an influential text that has shaped the work of scholars of logic for centuries. (shrink)

The tradition of Lughz and muʿammā in Arab poetry has an important place. Ibn al-Fāriḍ (d. 632/1235) is a divine love poet that lived in the Ayyubids period. He is an important point in the process of change and transformation of Arabic poetry language. This research aims to carry out a theoretical and anecdotal examination of the Lughzes in Ibn al-Fāriḍ’s Dīwān. The work explains, firstly, the concept of Lughz in terms of conceptual content and theoretical structure and summarizes its (...) own method to be applied in solving and evaluating Lughzes in ten articles. The paper indicates whether the Lughzes in Dīwānhave a theoretical structure or not. In this context, it distinguishes the Lughzes from the number of layers, simple and compound structure maintenance. It examines the theoretical and functional contributions of the tahsīl, takmīl, tashīland tazyīlmethods, the stages of the establishment and the solution of the Lughzes.Abstract: Abū Hafs Sharafuddīn Omar b. Ali al-Hamavī al-Mısrī (d. 632/1235) known as the king of lovers, and called Ibn al-Fārid, is a divine love poet that lived in Egypt during the Ayyubids period (1171-1462). He is an important figure in the process of change and transformation of poetry language in Arabic literature. The lughz and muʿammā (enigma, enigmetic speech, allusion, inversion riddle, poetry puzzle, synecdoche and metaphoric language) means a word pointing to a name or something by symbol and sign. Numerous books have been written about lughzes. These include Arabic poetry, Persian poetry, Classical Turkish poetry, Arabic grammar, Islamic law, hadith, mathematics and inheritance law. The lughz and muʿammā have some linguistic features related to phonetics, statistical linguistics, morphology, lexicology, grammar, syntax, semantics and prosody. This tradition has an important place in Arabic poetry. The research aims to carry out a theoretical and anecdotal examination of the lughzes and muʿammās in Ibn al-Fārız’s Dīwān. The paper explains, firstly, the concept of lughz in terms of conceptual content and theoretical structure. The article summarizes its own method to be applied in analyzing and evaluating lughzes within ten items. The research examines the series of lughzes in Dīwānand divides them into parts according to the original question in the riddles. This work examines the secondary lughzes given in the details of poems in solution parts. The paper indicates whether the lughzes in Dīwānhave a theoretical structure or not. In this context, the research examines lughzes in terms of language and structure, especially in terms of the processes of establishment and solution. This paper categorizes the lughzes according to the number of layers and to whether they have a simple or compound structure. This paper examines the theoretical and functional contributions of the amal al-tahsīlī, amal al-takmīlī, amal al-tashīlī and amal al-tazyīlī methods in the stages of the establishment and the solution of the lughzes. The work applies the theoretical perspectives of these methods to each lughz. The research also examines the contribution of these four methods to the lughzes.There are many lughzes in Ibn al-Fārid’s poems. In Ibn al-Fārid’s Dīwān, in general, fifty-four things are asked. Fifty-one of them are words. Three of them are verbs. One of the verbs is in the order structure and two in the past tense. His lughzes have a theoretical and methodical structure. In terms of organizational structure, lughzes are generally multi-layered, intricate, compound and integrated. Composite lughzes are multi-layered, simple poems are single-layered. Approximately twenty words are asked in the lughzes. These words are always in the first layer of lughz, whether simple or compound. Thirty-seven words in the lughz are secondary lughz with an auxiliary and complementary nature. They are located between the second and sixth layers. Seventeen of the lughzes asked in the auxiliary nature are located in the second layer, thirteen in the third layer, five in the fourth layer, one in the fifth layer and one in the sixth layer. One of the lughzes is six-layered, one of them are five-layered, four of them are four-layered, eight are three-layered, four are double-layered and three are single-layered. According to this, the majority of lughzes in Ibn al-Fārid’s poems are in the unified form and multilayered.The lughzes are formed in terms of word, composition, phrase, grammar and meaning levels. The lughzes have both lexical and semantic characteristics. Ibn al-Fārid uses the configuration (amal al-tahsīlī), completion (amal al-takmīlī), facilitation (amal al-tashīlī) and addition (amal al-tazyīlī) methods to design the lughzes. The structure in the lughzes is shaped by these methods. The words in his lughzes constitute eleven categories, consisting of names, acts and noun verbs. The answers of the questions asked in the poems consist in general of prophet names, surah names, tribal names, administrator’s surnames, letters, cities, animals, food and drink names, attributes and actions. Verbs are in the past time or order form. Some of the lughzes in Ibn al-Fārid’s poems are built in an extraordinary style beyond being interesting. Not all the sentences used in couplets are part of the lughzes. These elements are mentioned in order to complete the lughzes in terms of rhythm and meaning. To be able to solve the lughzes of Ibn al-Fārid, one must be knowledgeable about the language and narrative features of Arabic and Islamic culture, as well as subjects such as the Quran, Sufism, abjad calculation, mathematics, geometry, geography, biology, botany and zoology. His poems contributes to the development and transformation of Arabic poetry. (shrink)

Classical work on logic by a Muslim scholar ; includes comments and explanations by Sheikh Muḥammad ʻAbduh, edited and introduced by a modern scholar.

The Persian philosopher Ibn Sina (d. 1037), known in Europe as Avicenna, was arguably the greatest master of Aristotelian thought in the Muslim world. The symbolical 'Poem on the Soul' (Qasidat al-nafs), which portrays all earthly human souls as in temporary exile from heaven, is traditionally attributed to Avicenna, and was received with enthusiasm by its commentators. A highly significant commentary on the Qasida was written by?Ali b. Muhammad b. al-Walid (d. 1215 CE), a major early representative of the Tayyibi (...) Ismaili tradition, which emerged and flourished in medieval Yemen. In his view, the poem encapsulated Tayyibi beliefs, whose doctrines bear striking parallels with late antique Gnosticism. Avicenna's Allegory on the Soul presents the first edition of the Arabic text of Ibn al-Walid's commentary, 'The Useful Epistle' (al-Risala al-mufida), alongside an English translation and extended introduction. It offers invaluable insight into the intricacies of Muslim thought and a deeper understanding of Avicenna's substantial intellectual legacy. (shrink)

Farīd al-Dīn Abu al-Ḥasan ‘Alī b. al-Fahhād’s astronomical tradition as represented in the prolegomenon to his Alā’ī zīj (1172 AD) shows his experimental examination of the theories of his predecessors and testing the circumstances of the synodic phenomena as derived from the theories developed in the classical period of medieval Middle Eastern astronomy against his own observations. This work was highly influential in late Islamic astronomy and was translated into Greek in the 1290s. He evaluated al-Battānī’s Ṣābi’ zīj (d. 929 (...) AD) and al-Khāzinī’s Sanjarī zīj (fl. 1115 AD) with regard to the conjunction between Jupiter and Saturn in 1166 AD and found the errors of, respectively, about 35 and 10 days in the times predicted, which are verified by a recalculation on the basis of these works and modern theories. His inspection of the four solar theories established by his Islamic predecessors with respect to the quantitative differences between their predicted times for the occurrence of the vernal equinoxes is also correct. His calculation of the parameters of the solar and lunar eclipses in April 1176 has the errors of up to 1 h in the time and one digit in the magnitude. A general result of this study is that solely the evaluation of the synodic phenomena could mislead the judgment about the reliability and worthiness of the contemporary theories. (shrink)

The passionate and staunch defence of logic of the controversial thinker Ibn Ḥazm, Abū Muḥammad ʿAlī b. Aḥmad b. Saʿīd of Córdoba (384-456/994-1064), had lasting consequences in the Islamic world. Indeed, his book Facilitating the Understanding of the Rules of Logic and Introduction Thereto, with Common Expressions and Juristic Examples (Kitāb al-Taqrīb li-ḥadd al-manṭiq wa-l-mudkhal ilayhi bi-l-alfāẓ al-ʿāmmiyya wa-l-amthila al-fiqhiyya), composed in 1025-1029, was well known and discussed during and after his time; and it paved the way for the studies (...) of his compatriots Ibn Bājjah (d. 1138), Ibn Ṭufayl (1185), and Ibn Rushd (1198), who each gave demonstrative reasoning a privileged place within the methods of attaining knowledge. Unfortunately, as too often in the history of science, Ibn Ḥazm’s innovative perspectives and contributions in logic have been overlooked or considered with an attitude of contempt. On the one hand, his work has been seen, at best, as promulgating the benefits of studying Aristotle’s logic, so that his contribution is assessed as more didactical than conceptual. And on the other hand, those who do examine his innovations often consider them to be mistaken. As indicated by Chejne (1984, p. 2) contempt towards the logical work of Ibn Ḥazm was also present in its reception by the Eastern philosophers who accused him of deviating from Aristotelian logic and of dabbling in things beyond his capability. However, a reassessment of his work on logic has since begun, by delving into the ways the thinker of Córdoba studied the links between deontic and modal qualification of propositions. In this context Lameer’s (2013) paper on the logical sources of Ibn Ḥazm is worth mentioning; the author (p. 417, footnote 1) observes that, although, strictly speaking, it was al-Fārābī who first drew the parallelism between deontic and modal concepts, it was Ibn Ḥazm who developed it and worked it out in a more precise manner. A primary aim of this paper is to help fill some of these gaps by stressing the role of the work of Ibn Ḥazm in developing a notion of deontic necessity deeply rooted in legal normativity, and in explicitly discussing the transference between deontic and modal concepts. According to our view; the basic units of Islamic deontic logic are what we might call, indulging in terminological anachronism, heteronomous imperatives. As it turns out, the heteronomy of imperatives within Islamic legal systems contrasts with those of the purely moral realm, which seem to be closer to an autonomous conception of moral law. There it concurs again with Leibniz’s proposal to define obligatory as “what is necessary for a good person to do”. In the present paper, we will focus on the heteronomous imperatives of legal systems rather than on the imperatives of the purely moral realm. In this context, the work of Ibn Ḥazm extends the parallelism between the necessity of events and that of human actions stressed by his predecessors. According to our understanding, Ibn Ḥazm’s parallelism can be rendered explicit formally by means of a conditional (or hypothetical) structure shared by both deontic and modal propositions. Moreover, this structure makes apparent that this parallelism displays an underlying system of “degrees”. Indeed, while in the domain of events, given some conditions, it makes sense to distinguish between an event that is more likely to happen than another. Ibn Ḥazm speaks of near and distant possibility (such as the higher degree of likelihood of rain, given the condensation of clouds in December, and its lower degree, when the condensation occurs in summer); and, in the domain of actions, the Islamic notion of weighting actions determines degrees of virtue (or of legal and moral value). So whereas the degree of virtue of performing a forbidden act as determined by the distribution of sanction and reward is 0, we obtain the same value by pondering the likelihood of an impossible event to take place. Furthermore, as discussed in section II.3.2, the system of values at work in the parallelism can be seen as opening the way to a more direct correspondence. Thus, while in the realm of nature, likelihood of occurrence of an event is dependent upon the conditions specific to the occurrence of that event; while, in the realm of jurisprudence, likelihood of performing an action is dependent upon the distribution of reward and sanction specific to that action (being that, given the choice to perform or not perform a given action, those that will be rewarded are more likely to be performed than those that are not). According to this perspective, the point of the parallelism is that both deontic and modal qualifications measure the degree of an action or event to become actual; that is – indulging once more in anachronism (but this time from the Leibnizian background) – the degree measures how feasible (facile) an action or event may be. This suggests that Ibn Ḥazm’s perspectives already herald the links to probability and possibility explored by Leibniz six centuries later – see for example Leibniz’s (1671, A VI, I, p. 424-26) use of probability in the context of conditional right. Nevertheless, it also shows a crucial difference to the approach developed in the Elementa Jura Naturalis: whereas Leibniz’s studies seek to define what is to be just or virtuous, the logical system of deontic imperatives within Islamic jurisprudence presupposes that what is to be virtuous has already been settled. Determining what is to be virtuous is not achieved by logical reasoning within the system of legal jurisprudence, but by delving into the higher objectives of the Sharīʿa. While developing our point, we will delve into the logical structure of the heteronomous imperatives. This distinguishes our contribution from the existing literature, such as the papers of Chejne (1984), Lameer (2014), and Guerrero (1997, 2010, 2014), which do not provide a logical analysis of the deontic concepts put into work by Ibn Ḥazm. The true antecedent to the present paper is the work of Farid Zidani (2007, 2015), who, so far as we know, was the first to undertake such a task. Some of our own developments and general epistemological thoughts go beyond Ibn Ḥazm’s framework and motivations; mainly those contained in sections II.3.2 and IV. However, according to our view, these reflections suggest that Ibn Ḥazm’s approach has the substance for a broader and deeper exploration of the logic of norms. The paper is structured as follows:I.Ibn Ḥazm’s Logic of Heteronomous Imperatives. After presenting some extracts of the relevant text, we proceed by providing a formal reconstruction of the five forms of deontic modalities. II. A Landmark in the History of the Logical Analysis of Norms. Duties and Modalities. In this section, we study the transferences from deontic to modal necessity and possibility. We briefly compare the deontic system of Islamic Jurisprudence with that of Leibniz.III. Leibniz and Hypothetical Imperatives in Law.IV. Beyond Ibn Ḥazm: Conclusions and the Work Ahead. We will conclude the paper by discussing briefly some conceptual points that distinguish the logic of heteronomous imperatives from contemporary deontic logic. Our final words will discuss deontic-modal parallelism in the context of Ibn Ḥazm’s rejection of reasoning by conjecture and what we call “the internalization of nature.”. (shrink)

The Umayyads (41-132/661-750) were the first Muslim dynastic state established in Damascus after the Rasheedun Caliphs. The Umayyads' transformation of the caliphate into a sultanate, their tribalist and discriminatory approaches, as well as the exaggerated palace life and entertainment of some caliphs have been the subject of criticism. Among the Umayyad caliphs, Yazīd II (101-105/720-724) was remembered for his drinking parties and love affairs with his concubines, and his fondness for entertainment to the degree of debauchery was described. The night (...) life of the caliph in question with his concubines named Sallāma and Habābah and his inclusion of them in the administration did not escape attention.It is known that the Umayyads had some problems in their relations with the new non-Arab Muslims (mawālī). Yazīd II’s elder brother, al-Maslama İbn ʽAbd al-Malik, was prevented on the grounds that his mother was a mawāli, although he was known to be the most worthy candidate for the caliphate among his brothers. Yazīd II, on the other hand, was appointed as the heir apparent with the advantage of being a member of the dynasty on his mother's side and then he was brought to the caliphate.After ‘Umar ibn ʽAbd al-ʽAziz, who was recognised as the ‘Fifth Rasheedun Caliph’ thanks to his piety and effective administrative skills, Yazīd II, who had a completely opposite character and administrative understanding, was brought to the caliphate. Although he imitated ‘Umar ibn ʽAbd al-ʽAziz in the first days of his caliphate, this situation did not last long. Soon after, he came under the influence of his favourites named Sallāma and Habāba and started to govern the state under the influence of these two names. It has also been stated that he jeopardised the future of the state and the dynasty with his arbitrary practices and debauched life. The sources give limited information about the lives of Sallāma and Habābah. Sallāma was born in Mecca as the child of a family whose parents were slaves (muwellada). It is narrated that she memorised almost all poetry and song lyrics from the Jahiliyyah period until the time she lived, and that she was extremely knowledgeable in the al-Qur’ân al-Karîm, hadiths and religious sciences. But with her mesmerising voice and physical beauty, she became famous as a singing courtesan. She gained her real fame when she met Yazid ibn ʽAbd al-Malik and became a part of the palace life. After Yazid II became the caliph, she rose in the palace and started to have a say in the state administration. It has been stated that Habābah was not inferior to Sallāma with her physical beauty, superior performance in singing, knowledge and manners, and even more advanced. As a matter of fact, Yazīd II was enamoured of her at first sight and wanted her very much, but his brother Caliph Sulaymān prevented him. Henceforth Yazīd II seated these two combines on his right and left in his palace and did not leave them until his death.Sallāma was an extremely intelligent, knowledgeable and beautiful woman who could be called Yazīd II’s first love. She almost ruled the state by using the affection and trust that the caliph cherished for her. So much so that the highest bureaucrats of the state could only be appointed with her approval. With her beauty, voice, and sharp intelligence, Habābah also enchanted the caliph, and her intervention in the state administration cost the caliph his life. Yazīd II was very saddened by the sudden death of Habābah during an entertainment party. His body was kept waiting for days and could only be buried after the warning of the caliph’s elder brother al-Maslama. The caliph, who knew the cause of her death from himself, never left her grave day or night. Weeks after the burial, he had her grave opened, embraced and kissed her decomposed corpse, lamented, and it was recorded that he died of grief. This situation, which cost the caliph his life, was expressed as ‘lovesickness’.This information and details are mentioned in Islamic historical sources. In this study, by using classical (Arabic) sources, two of the women who we think were influential on politics are introduced. Thus, we have contributed to the discussions on the presence and role of women in state administration in an early period of Islamic history. In this study, the portraits of two women, Habāba and Sallāma, who we think were involved in politics during the Umayyad period, albeit limited to the reign of Yazīd II, are given. While their short biographies are discussed, the status of women in the Umayyads, palace life and entertainments are touched upon. Again, the concepts of concubine and qayna (singing concubine) and umm al-walad, which express their art and social status in the person of these two concubines are explained. (shrink)
