Yahya related to me from Malik from Yahya ibn Said from al-Qasimibn Muhammad that A'isha, the wife of the Prophet, may Allah bless himand grant him peace, said when asked whether it was permissible for aman to marry again a wife he had divorced irrevocably if she hadmarried another man who divorced her before consummating the marriage,"Not until she has tasted the sweetness of intercourse."
