The Book of Marriage (Kitab Al-Nikah)
Muslim :: Book 8 : Hadith 3359
'A'Asha (Allah be pleased with her) reported: A person divorced his wife by three pronouncements; then another person married her and he also divorced her without having sexual intercourse with her. Then the first husband of her intended to remarry her. It was about such a case that Allah's Messenger (may peace be upon him) was asked, whereupon he said: No, until the second one has tasted her sweetness as the first one had tasted.
