THE earliest biographers of the Arabian Prophet, whose works are extant in Arabic, are Ibn-Ishaq (A.H. 151), Ibn-Hisham (A.H. 218), Waqidi (A.H. 207), and Tabari (A.H. 310). Ismail Abulfida, Prince of Hamah, in Syria (A.H. 733), compiled a Life of Muhammad in Arabic, which was translated by John Gragnier, Professor of Arabic at Oxford (A.D. 1723), and into English by the Rev. W. Murray, Episcopal clergyman at Duffus, in Scotland.
