Maliks Muwatta Book 29, Hadith Number 57.

Section : Idda of Divorce and Divorce of Menstruating Women.

Yahya related to me from Malik that he had heard that Abu Bakr ibn Abd ar-Rahman and Sulayman ibn Yasar and Ibn Shihab used to say, “When the divorced woman enters the beginning of her third period, she is clearly separated from her husband and there is no inheritance between them and he has no access to her.”
