Al-Hakam ibn Abi al-`As ibn Umayyah (Arabic: الحكم بن أبي العاص / ALA-LC: al-Ḥakam bin Abī al-‘As) was the father of the Umayyad Caliph Marwan I and an uncle of Uthman. He is regarded as a Sahaba by Sunnis.[1]
When his nephew Uthman ibn Affan converted to Islam, Hakam bound and beat him.
Both Hakam and his son where sent to exile from Medina to Ta'if by Muhammad, saying they should never return. It is reported that Hadrath Uthman interceded with Muhammad for Hakam (Hadrath Uthman's paternal uncle) and his son Marwan. Muhammad agreed to rescind the orders of exile but before the order were passed Muhammad died. During the time of the first two caliphs as no evidence other than the evidence of Hadrath Uthman was available regarding rescinding of the orders Hakam and Marwan were not called back (typically in Islamic jurisprudence two evidences are required) . Uthman as Caliph recalled Marwan or both of them.[2][3]
Hakam was the grandson of Umayya ibn Abd Shams, for whom the Umayyad clan is named. His father was Abu al-'As ibn Umayya. His brother was Affan ibn Abi al-'As the father of Uthman, the third Sunni Caliph, and his son Marwan ibn al-Hakam was the eighth Sunni Caliph.
Saffya bint abi al-A'as, al-Hakam's sister, is the wife of Abu Sufyan and the mother of Ramlah bint Abi-Sufyan, a wife of Muhammad. He also had brother named Uthman.
