Sahih Muslim Book 8, Hadith Number 3356.

Chapter: It is not permissible to marry a woman, who is divorced by three pronouncements until she is married to another, man and he has a sexual intercourse with her, and then he abandons her and she completes her ‘Idda.

‘Aisha (Allah be pleased with her) reported that Rifa’a al Qurazi divorced his wife and afterwards Abd al-Rahman b. al-Zubair married her. She came to Allah’s Apostle (may peace he upon him) and said: Messenger of Allah, Rifa’a has divorced me by three pronouncements. (The rest of the hadith is the same.)
