Yahya related to me from Malik that Muhammad ibn Abi Umama ibnSahl ibn Hunayf heard his father say, "My father, Sahl ibn Hunayf dida ghusl at al-Kharrar. He removed the jubbah he had on while Amir ibnRabia was watching, and Sahl was a man with beautiful white skin. Amirsaid to him, 'I have never seen anything like what I have seen today,not even the skin of a virgin.' Sahl fell ill on the spot, and hiscondition grew worse. Somebody went to the Messenger of Allah, mayAllah bless him and grant him peace, and told him that Sahl was ill,and could not go with him. The Messenger of Allah, may Allah bless himand grant him peace, came to him, and Sahl told him what had happenedwith Amir. The Messenger of Allah, may Allah bless him and grant himpeace, said, 'Why does one of you kill his brother? Why did you notsay, "May Allah bless you?" (ta baraka-llah) The evil eye is true. Dowudu from it.' Amir did wudu from it and Sahl went with the Messengerof Allah, may Allah bless him and grant him peace, and there wasnothing wrong with him."
