Hazrat Abu Al-Wadain narrates that once a man married the daughter of a man from Syria, whose title was "Ibnat Muheerah" (she was called Muheerah because her dowry was high). But on the wedding night, he was presented with another daughter whose title was "Ibnat Fataah" (her dowry was less). When the man had intercourse with the girl that night, he asked, "Who are you?" She replied, "I am Ibnat Fataah." The man said, "Your father married me to Ibnat Muheerah." So they took their case to Hazrat Muawiyah bin Abi Sufyan (may Allah be pleased with him). Hazrat Muawiyah (may Allah be pleased with him) said, "A woman has been exchanged for a woman, so there is no dispute." Hazrat Muawiyah (may Allah be pleased with him) consulted the Syrian scholars present with him about this matter, and they also gave the same verdict. Then the man said, "I want to take this case to Hazrat Ali (may Allah be pleased with him)." Hazrat Muawiyah (may Allah be pleased with him) permitted him. The case was presented before Hazrat Ali (may Allah be pleased with him), so he picked up a trivial thing from the ground and said, "For me, deciding this case is even more trivial than this thing." The woman will receive as much dowry as you paid her to make her private parts lawful for you. And it is obligatory upon her father to give the other daughter the wealth that you paid, and you should not go near her until the first girl completes her waiting period ('iddah). The narrator says, "I think Hazrat Ali (may Allah be pleased with him) had the girl's father flogged or intended to have him flogged."
