Mu'awiyah bin Abi Ayyash al-Ansari (may Allah be pleased with him) said that he was sitting with Abdullah bin al-Zubayr and Asim bin Umar (may Allah be pleased with them both). The narrator said: Muhammad bin Iyas bin al-Bukayr (may Allah have mercy on him) came to them both and said: "A man from the desert has given his wife three divorces before consummating the marriage. What is your view about it?" Abdullah bin al-Zubayr (may Allah be pleased with him) said: "We have nothing to say about this. Go to Abdullah bin Abbas and Abu Hurayrah (may Allah be pleased with them both), whom I left with Aishah (may Allah be pleased with her); ask them, and then come and tell us too." So Muhammad bin Iyas bin al-Bukayr (may Allah have mercy on him) went and asked them. Abdullah bin Abbas (may Allah be pleased with him) said to Abu Hurayrah (may Allah be pleased with him): "Give him a ruling, for a difficult question has come to you." Abu Hurayrah (may Allah be pleased with him) said: "One divorce separates the wife, and three divorces make her forbidden." Abdullah bin Abbas (may Allah be pleased with him) said the same: "until she marries another husband."
