Aisha (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 @@@ual 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 tested
