Miswar b. Makhramali reported that he heard Allah's Messenger (ﷺ) say, as he sat on the pulpit:The sons of Hisham b. Mughira have asked my permission to marry their daughter with 'Ali b. Abi Talib (that refers to the daughter of Abu Jahl for whom 'All had sent a proposal for marriage). But I would not allow them, I would not allow them, I would not allow them (and the only alternative possible is) that 'Ali should divorce my daughter (and then marry their daughter), for my daughter is part of me. He who disturbs her in fact disturbs me and he who offends her offends me
