Ayoub bin Sulaiman bin Bilal أيوب بن سليمان بن بلال · The Book of Marriage

It was narrated from Abu Hurairah that the Messenger of Allah said: "There are three who are promised the help of Allah: The Mukatab who wants to buy his freedom, the one who gets married seeking to keep himself chaste, and the Mujahid who fights in the cause of Allah." *Mukatab: the slave who has made a contract of manumission.

"I got married to Fatimah, may Allah be pleased with her, and I said: 'O Messenger of Allah, let me consummate the marriage.' He said: 'Give her something.' I said: 'I do not have anything.' He said: 'Where is your Hutami armor?' I said: 'It is with me.' He said: 'Give it to her.'"
