322/933-934) and one of the greatest Isma`ili missionaries.[^25] He reproduced controversies between him and al-Razi in his A`lam al-Nubuwwah .[^26] Thanks to this book, al-Razi's ideas about prophets and religion are preserved for us.
Ibn al-Tammar, whom Kraus believes to be perhaps Abu Bakr Husain al-Tammar.[^27] He was a physician and had some controversies with al-Razi as is reported by Abu Hatim al-Razi in A`lam al-Nubuwwah .[^28] Ibn al-Tammar refuted al-Razi's al-Tibb al-Ruhani and al-Razi answered this refutation.[^29] In fact, al-Razi wrote two refutations: (a) refutation of al-Tammar's refutation of Misma`i concerning matter; (b) refutation of al-Tammar's opinion on the atmosphere of subterranean habitations.[^30] Those of whom we know from the titles of the books written by al-Razi: (a) al-Misma'i, a Mutakallim who had written against the materialists and against whom al-Razi wrote a treatise;[^31] (b) Jarir the doctor who had a theory about the eating of black mulberry after water-melon;[^32] (c) al-Hasan ibn Mubarik al-Ummi, to whom al-Razi wrote two epistles;[^33] (d) al-Kayyal, a Mutakallim, against whose theory of the Imam, al-Razi wrote a book; [^34] (e) Mansur ibn Talhah, who wrote a book on “Being” refuted by al-Razi;[^35] (f) Muhammad ibn al-Laith al-Rasa'ili whose writing against alchemists was answered by al-Razi.[^36] Ahmad ibn al-Tayyib al-Sarakhsi (d.
286/899), an elder contemporary of al-Razi. Al-Razi refuted him on the question of bitter taste;[^37] Al-Razi refuted also his master, Ya`qub ibn Ishaq al-Kindi, who had written against the alchemists.[^38] We should add to all those known by names many others who were refuted by al-Razi, especially the Mu'tazilah and different Mutakallimin.[^39] Works AI-Razi's books are very numerous.
He himself prepared a catalogue of his books, reproduced by Ibn al-Nadim.[^40] Here we find: 118 books, 19 epistles, then 4 books, 6 epistles, and one maqalah , the total being 148 works. After Ibn al-Nadim, al-Biruni wrote an epistle on the bibliography of al-Razi. This epistle, found in a unique manuscript in Leiden,[^41] was edited by Paul Kraus,[^42] and translated into German by J.
Ruska in his article: “al-Biruni als Quelle fur das Leben and die Schriften al-Razi's.”[^43] This catalogue is preceded by a short note on al-Razi's life.
