Ibn Abi Mulaykah (may Allah have mercy on him) says that Sayyiduna Aqil bin Abi Talib (may Allah be pleased with him) married Fatimah bint Utbah (may Allah be pleased with her). She said: Bear with me, and I will spend on you. Whenever he went in to her, she would say: Where is Utbah bin Rabi'ah, and where is Shaybah bin Rabi'ah? He said: When you enter Hellfire, they will be on your left. So she wrapped her clothes tightly about her and came to Sayyiduna Uthman bin Affan (may Allah be pleased with him) and mentioned this to him. He appointed Sayyiduna Abdullah bin Abbas and Sayyiduna Mu'awiyah (may Allah be pleased with them both) as arbiters. Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: I will separate them. Sayyiduna Mu'awiyah (may Allah be pleased with him) said: I will not separate two elders of Banu Abd Manaf. When they came to them, they found that the two had wrapped their clothes about themselves and had settled their affair between themselves.
(b) Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: Sayyiduna Mu'awiyah (may Allah be pleased with him) and I were arbiters, and we were told: If you see fit to separate them or to unite them, then give that decision.
