Wedlock, Marriage (Nikaah)

Bukhari :: Book 7 :: Volume 62 :: Hadith 157

Narrated Al-Miswar bin Makhrama:

I heard Allah's Apostle who was on the pulpit, saying, "Banu Hisham bin Al-Mughira have requested me to allow them to marry their daughter to Ali bin Abu Talib, but I don't give permission, and will not give permission unless 'Ali bin Abi Talib divorces my daughter in order to marry their daughter, because Fatima is a part of my body, and I hate what she hates to see, and what hurts her, hurts me."
