It was reported from Abu Umaamah ibn Sahl ibn Hunayf that his father told him that the Messenger of Allaah (peace and blessings of Allaah be upon him) went out and they travelled with him towards Makkah until they reached Shi’b al-Khazzaar in al-Juhfah.
Sahl ibn Hunayf washed himself, and he was a white man with a handsome body and skin. ‘Aamir ibn Rabee’ah, the brother of Bani ‘Udayy ibn Ka’b, looked at him when he was washing, and said, “I have never seen anything like this, not even the skin of a virgin in seclusion!” (this was a metaphor for the intense whiteness of his skin).
Then Sahl suffered a seizure (an epileptic fit, in which he fell to the ground). He was brought to the Messenger of Allaah (peace and blessings of Allaah be upon him) and it was said, “O Messenger of Allaah, do you know what has happened to Sahl? By Allaah, he cannot raise his head and he will not wake up.” He said, “Do you accuse anyone with regard to him?” They said, “‘Aamir ibn Rabee’ah looked at him.” So the Messenger of Allaah (peace and blessings of Allaah be upon him) called ‘Aamir and spoke angrily with him, saying, “Would any of you like to kill his brother? If you see something that you like, why do you not pray for blessing for it?” Then he said to him (‘Aamir), “Do ghusl for him.” So he washed his face, hands, elbows, the soles of his feet and inside his izaar (lower garment) from a vessel, then that water was poured over him (Sahl) – a man poured it over his head and back from behind, tilting the vessel.
This was done to him, then Sahl went on with the people and there was nothing wrong with him.
