Ali ibn Abi Talib · The Book of Marriage

"The Messenger of Allah forbade taking a woman as a co-wife to her paternal aunt or maternal aunt."

"If she let him do that, I will flog him with one hundred stripes , and if she did not let him, I will stone him (to death)."

"I will pass the same judgment concerning her as the Messenger of Allah did. If she let you do that, I will flog you, but if she did not let you do that, I will stone you (to death)." She had let him do that so he flogged him with one hundred stripes. (One of the narrators) Qatadah said: "I wrote to Habib bin Salim and he wrote back to me with this information."

"The Messenger of Allah said: 'What differentiates between the lawful and the unlawful is the Duff, and the voice (singing) for the wedding.'"

"The Messenger of Allah married me when I was six, and consummated the marriage with me when I was nine, and I used to play with dolls."
