Narrated Sahl bin Sa'd As-Sa'idi: Uwaimir Al-Ajlani came to 'Asim bin 'Adi and said, "If a man found another man with his wife and killed him, would you sentence the husband to death (in Qisas,) ie, equality in punishment)? O 'Asim! Please ask Allah's Messenger ﷺ about this matter on my behalf"'.Asim asked the Prophet ﷺ but the Prophet disliked the question and disapproved of it'.Asim returned and informed Uwaimir that the Prophet disliked that type of question. Uwaimir said, "By Allah, I will go (personally) to the Prophet". Uwaimir came to the Prophet ﷺ when Allah had already revealed Qur'anic Verses (in that respect), after 'Asim had left (the Prophet ﷺ ). So the Prophet ﷺ said to Uwaimir, "Allah has revealed Qur'anic Verses regarding you and your wife". The Prophet ﷺ then called for them, and they came and carried out the order of Lian. Then Uwaimir said, "O Allah's Messenger ﷺ! Now if I kept her with me, I would be accused of telling a lie". So Uwaimir divorced her although the Prophet ﷺ did not order him to do so. Later on this practice of divorcing became the tradition of couples involved in a case of Li'an. The Prophet ﷺ said (to the people)".Wait for her! If she delivers a red short (small) child like a wahara (a short red animal). then I will be of the opinion that he (Uwaimir) has told a lie but if she delivered a black big-eyed one with big buttocks, then I will be of the opinion that he has told the truth about her"'.Ultimately she gave birth to a child that proved the accusation.
