BaiḌĀwĪ (‛Abdallah ibn ‛Umar al-Baiḍāwī), Mahommedan critic, was born in Fars, where his father was chief judge, in the time of the Atabek ruler Abu Bakr ibn Sa‛d (1226-1260). He himself became judge in Shiraz, and died in Tabriz about 1286. His chief work is the commentary on the Koran entitled The Secrets of Revelation and The Secrets of Interpretation (Asrār ut-tanzīl wa Asrār ut-ta' wīl). This work is in the main a digest of the great Mu‛tazalite commentary (al-Kashshāf) of Zamakhsharī (q.v.) with omissions and additional notes. By the orthodox Moslems it is considered the standard commentary and almost holy, though it is not complete in its treatment of any branch of theological or linguistic knowledge of which it treats, and is not always accurate (cf. Th. Nöldeke's Geschichte des Qorans, Göttingen, 1860, p. 29). It has been edited by H. O. Fleischer (2 vols., Leipzig, 1846-1848; indices ed. W. Fell, Leipzig, 1878). There are many editions published in the East. A selection with numerous notes was edited by D. S. Margoliouth as Chrestomathia Beidawiana (London, 1894). Many supercommentaries have been written on Baiḍāwī's work.
He was also the author of several theological treatises.
