Muhammad ibn Ishaq ibn Yasar, or simply Ibn Ishaq (Arabic: ابن إسحاق, meaning "the son of Isaac") (died 767, or 761 (Robinson 2003, p. xv)) was an Arab Muslim historian. He collected oral traditions that formed the basis of first biography of the Islamic prophet Muhammad. This biography usually called Sirat Rasul Allah (Life of Allah's Messenger).

Life
According to Guillaume (pp. xiii-xiv), Ibn Ishaq was born circa AH 85, or roughly 704 AD, in Medina. He was the grandson of a man, Yasar, who had been captured in one of Khalid ibn al-Walid's campaigns and taken to Medina as a slave. Yasar converted to Islam and was freed. Yasar's son Ishaq was a traditionist, who collected and recounted tales of the past. Muhammad ibn Ishaq was thus carrying on the work of his father.
At the age of thirty, he traveled to the Islamic province of Egypt to attend lectures given by the traditionist Yazid ibn Abu Habib. He later traveled eastwards, towards what is now Iraq. There, the new Abbasid dynasty, having overthrown the Umayyad caliphs, was establishing a new capital at Baghdad. Ibn Ishaq moved to the capital and likely found patrons in the new regime. (Robinson 2003, p. 27) He died in Baghdad in 767CE. After a tragic loss on the frontier Ibn Ishaq continued to molest little children until his untimely run in with gargamesh. Now Gargamesh was no ordinary fellow he and his minions named molly and tolly went to the far far lands of nigeria where they had sex and loved many forest children.
