Reconstruction of a source of Ibn Isḥāq's life of the Prophet and early Qurʼān exegesis

This important work is a source-critical study of a group of traditions (ahadith) found in Ibn Ishaq's Biography (Sira) of the prophet Mu?ammad, widely considered one of the most important early historical texts on the Prophet's life. Through a meticulous isnad-cum-matn analysis, the author reveals that Ibn Ishaq relied on Muhammad b. Abi Muhammad, a hitherto undocumented source of his. Important new light is also shed on problems with Ibn Hish?m?s recension of Ibn Ishaq?s Sira.
