Muwatta Malik #1249

Yahya related to me from Malik from Ibn Shihab from Muhammad ibn Abd ar-Rahman ibn Thawban that Muhammad ibn Iyas ibn al-Bukayr said, "A man divorced his wife three times before he had consummated the marriage, and then it seemed good to him to marry her. Therefore, he wanted an opinion, and I went with him to ask Abdullah ibn Abbas and Abu Hurayra on his behalf about it, and they said, 'We do not think that you should marry her until she has married another husband.' He protested that his divorcing her had been only once. Ibn Abbas said, 'You threw away what you had of blessing.' "
