Sahl b. Sa'd as-Sa‘idi told that ‘Uwaimir al-'Ajlani asked God’s Messenger:“Tell me about a man who finds a man along with his wife. Should he kill him and then be killed by you1, or how should he act?” He replied,“A revelation has been sent down about you and your wife2, so go away and bring her.”Sahl said that they cursed one another in the mosque and that he was along with the people who were with God’s Messenger. Then when they finished ‘Uwaimir said,“I shall have lied against her, Messenger of God, if I keep her,”and pronounced her divorce three times. God’s Messenger then said to the people,“Look, and if she bears a child which is black, and has very black eyes, large buttocks and fat legs, I cannot but imagine that ‘Uwaimir has spoken the truth about her; but if she bears a reddish child like the lizard with red spots (wahara), I cannot but imagine that ‘Uwaimir has lied against her.”She gave birth to a child like that described by God’s Messenger in declaring that ‘Uwaimir had spoken the truth, and afterwards its lineage was traced to its mother. (Bukhari and Muslim.) 1. Some texts read as translated above; others use the third person, with reference to the family of the man and their revenge for killing him. 2. Al-Qur'an 24:6.
