Maliks Muwatta Book 29, Hadith Number 43.
Section : Divorce of Sick Men.
Yahya related to me from Malik from Yahya ibn Said that Muhammad ibn Yahya ibn Habban said, “My grandfather Habban had two wives, one from the Hashimites and one from the Ansars. He divorced the Ansariyya while she was nursing, and a year passed and he died and she had still not yet menstruated. She said, ‘I inherit from him. I have not menstruated yet.’ The wives quarrelled and went to Uthman ibn Affan. He decided that she did inherit, and the Hashimiyya rebuked Uthman. He said, ‘This is the practice of the son of your paternal uncle. He pointed this out to us.’ He meant Ali ibn Abi Talib.”
