Abbas ibn Abd al-Muttalib

al-Abbas ibn `Abd al-Muttalib (566 - 652) was an uncle of Muhammad. He was only born a few years before his nephew, and was one of Muahmmad's father's youngest brothers. He initially did not accept Islam, but did so later and got along well with his nephew. Through his son Abdullah ibn Abbas, the later Abbasid dynasty would claim the title of caliph (literally "successor to the prophet.")

He is buried at the Jannat al-Baqi cemetery in Medina.
