Yahya related to me from Malik from Yahya ibn Said from Bukayr
ibn Abdullah al-Ashajj from an-Numan ibn Abi Ayyash al Ansari from Ata
ibn Yasar that a man came and asked Abdullah ibn Amr ibn al-As about a
man who divorced his wife three times before he had had intercourse
with her Ata said, "The divorce of the virgin is one. Abdullah ibn Amr
ibn al-As said to me, 'You say one pronouncement separates her and
three makes her haram until she has married another husband.' "
