Yahya related to me from Malik from Yazid ibn Khusayfa that Amr ibn Abdullah ibn Kab as-Salami told him that Nafi ibn Jubayr told him that Uthman ibn Abi al-As came to the Messenger of Allah, may Allah bless him and grant him peace. Uthman said that he had a pain which was enough to kill him. The Messenger of Allah, may Allah bless him and grant him peace, said, "Rub it with your right hand seven times and say, I take refuge with the might of Allah and His power from the evil of what I feel. " Uthman added, "I said that, and Allah removed what I had. I still command my family and others to say it."
