After Al-Hijra
When Muhammad migrated from Mecca to Medina, his daughter Zaynab could not bear to leave her non-Muslim husband Abu al-'Aas, and was not required to do so until years later under other circumstances. Muhammad did not automatically divorce them.
One source states:
- At one time there were three girls living in the household of Khadija. Their names were Zainab, Ruqayya and Umm Kulthoom. Zainab, the eldest of the three, was married to one Abul-'As ibn er-Rabi' of Makkah. This man fought against the Prophet in the battle of Badr, and was captured by the Muslims. To ransom his freedom, his wife sent to the Prophet, a necklace which at one time had belonged to Khadija, and she had given it to her as a present on her marriage. Abul-'As was set free; he returned to Makkah, and sent Zainab to Medina as he had promised to do. Zainab, however, died soon after her arrival in Medina. Later, Abul-'As also went to Medina, accepted Islam, and lived with the Muslims.
