al-Aswad bin Yazid الأسود بن يزيد بن قيس النخعي · The Book of Marriage

It was narrated that 'Aishah, may Allah be pleased with her, said: "The Messenger of Allah gave his wives the choice (of staying with him) was it divorce?"

Zainab bint Jahsh used to boast to the other wives of the Prophet and say: "Allah married me to him from above the Heavens." And the Verse of Hijab was revealed concerning her.

"The dowry, when the Messenger of Allah was among us, was ten Awaq."
