Ibn Ishaq (d. 768)
Ibn Ishaq's writing was primarily concerned with the biography of Prophet Muhammad (pbuh) (Sirat Al-Rasul Allah) and the first wars of Islam (Al-Maghazi). Muhammad Ibn Ishaq related the first known biography (Sira) of the Prophet (pbuh). This work no longer exists in its original form, but has been preserved in at least two recessions, one of these recessions being authored by Ibn Hisham, thus Ibn Hisham's work represents one of the best existing authorities on the life of the Prophet (pbuh).
