Hazrat Alqama narrates that Hazrat Abdullah bin Masood said: One night while we were in the mosque, suddenly a man came and said, "If a person finds a man with his wife and kills him, will you kill that person? Or if he accuses her, will you flog him?" I will surely mention this matter before the Prophet Muhammad (peace and blessings be upon him). So when the Prophet Muhammad (peace and blessings be upon him) arrived, that man mentioned this matter before him, and the Prophet (peace and blessings be upon him) remained silent. Meanwhile, the verse of Li'an was revealed. The Prophet Muhammad (peace and blessings be upon him) called that man and recited these verses to him. After that, the man came and accused his wife. So the Messenger of Allah (peace and blessings be upon him) decided that both of them should perform Li'an, and he (peace and blessings be upon him) said: "It is likely that this woman will bring forth a dark, small child." So indeed, the woman brought forth a dark, small child.
