Maliks Muwatta Book 29, Hadith Number 56.

Section : Idda of Divorce and Divorce of Menstruating Women.

Yahya related to me from Malik from Nafi and Zayd ibn Aslam from Sulayman ibn Yasar that al-Ahwas died in Syria when his wife had begun her third menstrual period after he had divorced her. Muawiya ibn Abi Sufyan wrote and asked Zayd ibn Thabit about that. Zayd wrote to him, “When she began her third period, she was free from him and he was free from her, and he does not inherit from her nor she from him.”
