Islamic ideology and teachings about various trades and transactions in day to day life.

: Three unpublished ayyubid letters are presented here. They are addressed to ascetics, fuqarāʾ and ṣūfī, residing in the great mosque of Damascus, and devoted to reading the Qurʾān and praying at the tomb of prophet Zakariyyāʾ. This veneered shrine or ziyāra had been ignored until now, although it was known and it is common knowledge nowadays, that some rituals took place around the location where the head of John the Baptist, known in the lands of Islamic world as Yaḥyā (...) b. Zakariyyāʾ, was kept. Our research seeks to present aspects of the rituals held in the tomb of Zakariyāʾ, arguing that it was initially established with an impetus from Saladin, then thrived under his ayyubid successors, to start dwindling until it was abandoned by the end of the mamluk era.

This article offers the first edition and translation of two heretofore unpublished pharmacological treatises by Abū Bakr al-Rāzī, namely Fī ittikhādh māʾ al-jubn and Fī manāfiʿ māʾ al-jubn, which seem to have formed part of a lost volume on dairy products. As it demonstrates, al-Rāzī’s examination of whey is connected to his philosophical interest in the complex nature of simple substances such as milk. The article also highlights how these two treatises built on the Greek pharmacological tradition by incorporating ingredients (...) from Persia and India. (shrink)

Abū Bakr Muḥammad bin Zakariyya’ al-Rāzī (865–925) is generally known as a freethinker who argued against prophecy and revealed religion based on arguments from fairness of God and rationality. Recently some scholars argued that Razi was not as radical as the general interpretation takes him to be. Both the freethinker and conservative interpretations seem well supported based on difference bodies of evidence. However, the evidence is based on secondhand reports. In this paper I argue there is an interpretation of (...) prophecy which is supported by primary sources and can reconcile these putatively contradictory positions. Under my interpretation Razi allows for prophecy based on the rationality of moral deference in certain circumstances. In this picture one function of prophets is to act as moral experts for deference. This interpretation provides a synthesis of the freethinker and conservative views. Razi is conservative in having room for prophecy because of his dualist nature of humanity, and Razi is still a freethinker who values reason above all, because moral expertise requires excellent command of reason.

The fame of the Jacobite Christian Abu Zakariyya Yahya ibn ''Adi (893 bis 974) as in influential philosopher and as en eminent apologist of the Christian faith has been founded on reputation rather than on the study of his work. When Augustin Perier compiled the first list of his writings in 1920, most of his philosophical works were believed to be lost. Most recent publications have enabled us to appraise his merits as a translator an commentator of Aristotle. But (...) only a few of his philosophical monographs were available until an important collection of his treatises was discovered inthe libraries of Tehran. This. at last, has enabled us to study in detail his contribution to logic, his treatment of physical and metaphysical problems, and his position on questions of Muslim "kalam". The Monophysite theology of Yahya ibn ''Adi, on the other hand, though better known through the studies of G Graf and A. Perier, still awaits renewed examination. The most important works in this field have not even been published. So the new inventory of his writings is intended to provide the basis for a reassessment of his merits as an Aristotelean as well as a Christian thinker.The study contains a survey of biographical data, detailed bibliographical information on manuscripts and printed works and summaries of most the unpublished texts.

This paper introduces two newly discovered epistles by the celebrated physician and philosopher Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī. The first epistle addresses the question of why and how clothing can be used both to stay warm and to stay cool, drawing on the Aristotelian tradition of problem literature. The second epistle arises out of a court polemic and treats the question of whether one should consume mulberries after watermelons. This study offers analysis, editions, and translations of these previously unknown (...) epistles, situating them within their broader literary and cultural contexts. (shrink)

El presente artículo versa sobre Abū Zakariyyāʾ Yaḥyà al-Balansī, un discípulo fervoroso y distinguido del conocido maestro sufí Ibn Sabʿīn de Ricote. Hay poca información sobre Yaḥyà, y quizás por ello ha pasado desapercibido. En el trabajo se recogen estos datos para darlo a conocer. Yaḥyà al-Balansī (o algún antepasado suyo cercano) habría nacido en Valencia. Estuvo en Alejandría en compañía del šayḫ Abū l-Ḥasan al-Šāḏilī, quizás a partir del año 642/1244. Regresó a al-Andalus y, después, habría viajado nuevamente hacia (...) el Magreb. En Bugía, se encontró con Ibn Sabʿīn, en fecha desconocida, aunque debió de haber sido hacia el año 648/1250. Desde entonces se hizo discípulo incondicional suyo. Habría acompañado a Ibn Sabʿīn, hasta establecerse en La Meca, después de pasar por Túnez y Egipto. También estuvo en Medina y en el Líbano. Se deduce que Yaḥyà era un sufí viajero, al igual que Abū l-Ḥasan al-Šuštarī. Yaḥyà falleció en el año 665/1267 y fue enterrado en al-Balyana, en el Alto Egipto. En este trabajo se presentan los fragmentos de las pocas obras que nos han llegado, y se busca confirmar su autoría de Kitāb al-Sulūk fī ṭarīq al-qawm, la única epístola suya que se conserva completa. Al final, se traducen los fragmentos tanto de al-Wirāṯa al-muḥammadiyya, y un fragmento recogido por Ibn al-Ṭawwāḥ, como de otro fragmento que aparece al final de una Risāla de Ibn Sabʿīn. Del estudio de este acopio de datos se llega a dos conclusiones de relevancia: 1. Aunque en el encabezado de Kitāb al-Sulūk, Yaḥyà se presenta como hijo de Ibn Sabʿīn, en este trabajo se va a demostrar que no lo era. 2. Se confirma su autoría de Kitāb al-Sulūk. (shrink)

As there are several famous al-Rāzī relevant to philosophy, I need first to specify that this remarkable book deals with Abū Bakr Muhammad ibn Zakariyyā' al-Rāzī, also known as "Galen of the Arabs," and in Latin as well as in the Canterbury Tales as "al-Rhazes." He proudly presented himself as both a philosopher and a physician taking Galen as his model. Just as in Hellenistic times Galen was highly valued as a physician but demeaned as a philosopher, so often was (...) al-Rāzī. This book reinstates al-Rāzī as an interesting philosopher, who claims to be a disciple of Galen and Plato but clearly understands that discipleship implies following Galen's own example of avoiding uncritical...

There is a moment in The Immortal Life of Henrietta Lacks that brought tears to my eyes. Henrietta Lacks is the woman whose cervical tumor gave rise to a cell line—brand named HeLa—that became quite useful in many important lines of biomedical research. When the book’s author, Rebecca Skloot, tracks down Lacks’s descendents in a Baltimore ghetto, they are not doing well. Zakariyya, the youngest of her children, has had the toughest life. He was born after his mother’s cancer (...) was already widespread, and she died shortly after his birth. He has drifted in and out of the military and in and out of jail. A moody and violent man, he once killed a man over a girl by stabbing him in the chest with a kitchen knife. Skloot .. (shrink)

Nuestro propósito aquí es el de dar cuenta, de un modo sumario, de la figura de Abu Bakr Zakariyya al-Razi (el Rhazes de los latinos) y los posibles orígenes de su pensamiento, así como presentar la originalidad de su pensamiento filosófico en el contexto de su tiempo y su cultura.
