Abu al-As ibn al-Rabi'

Abu al-As ibn al-Rabi' (Arabic: أبو العاص بن الربيع‎, ’Abū al-‘Āṣ ibn al-Rabī‘, died in February, 634 AD) was a son-in-law and companion of the Islamic prophet Muhammad. His original name was said to have been Hushaym or Yasser.

He was the son of Hala bint Khuwaylid. His legal father was Al-Rabi ibn Abduluzza of the Abdshams clan of the Quraysh tribe; but he was known as a "bastard". He became a successful merchant and was considered an important person in Mecca.

His aunt Khadija regarded him as her son, and he frequently visited her home. In due course Khadija asked her husband Muhammad to find him a wife. Muhammad gave Abu al-As their eldest daughter, Zaynab, apparently with some reluctance. Later, however, he spoke "warmly" of Abu al-As, "who told the truth and kept his promises" and in whom he "found no fault as an in-law." Abu al-As and Zaynab had two children: Ali, who died in childhood, and Umama, who was later married to the fourth Caliph Ali.

When Muhammad, after declaring himself to be a prophet, lost popularity in Mecca, the Quraysh pressured Abu al-As to divorce Zaynab, saying they would give him any woman he liked in exchange. But Abu Al-As replied that he did not want any other woman and he remained with Zaynab. However, he refused to become a Muslim. Since Muhammad had no power of jurisdiction over Mecca, he too was unable to force his daughter to separate from her unbelieving husband. When the Muslims emigrated to Medina, Zaynab, although a convert, remained in Mecca with Abu al-As.
