It is narrated from Hazrat Sahl (may Allah be pleased with him) that Hazrat Uwaymir (may Allah be pleased with him) once came to Asim bin Adi (may Allah be pleased with him) and said, "Ask the Noble Prophet (peace and blessings be upon him) about this issue: if a man finds another man with his wife and kills him, will he also be killed in retaliation, or what will be done with him?" Asim (may Allah be pleased with him) asked the Noble Prophet (peace and blessings be upon him) about this issue, but the Noble Prophet (peace and blessings be upon him) did not like this question. Later, Uwaymir (may Allah be pleased with him) met Asim (may Allah be pleased with him) and asked, "What happened?" Asim (may Allah be pleased with him) replied, "What could have happened? You did not tell me a good thing. I asked the Noble Prophet (peace and blessings be upon him), but he did not like the question." Uwaymir (may Allah be pleased with him) said, "By Allah! I will go myself to the Noble Prophet (peace and blessings be upon him) and will definitely ask him this question." So he presented himself in the court of Prophethood, and by that time, revelation had already come to the Noble Prophet (peace and blessings be upon him) regarding this matter. Therefore, the Noble Prophet (peace and blessings be upon him) called both husband and wife and had them perform li'an (mutual cursing). Then Uwaymir (may Allah be pleased with him) said, "O Messenger of Allah! If I take her with me, it will mean that I have wronged her." So, even before the Noble Prophet (peace and blessings be upon him) gave the order, he separated from his wife (divorced her), and this became the practice among those who performed li'an. Then the Noble Prophet (peace and blessings be upon him) said, "Take care of this woman. If she gives birth to a child who is dark-skinned, with black eyes and large buttocks, then I will consider Uwaymir truthful. And if she gives birth to a child who is reddish in complexion and resembles a lizard, then I will consider him a liar." So, the child that was born to her had the undesirable traits (about which the Noble Prophet, peace and blessings be upon him, had said that if the child is born with these traits, then I will consider Uwaymir truthful).
