It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: When we intended to wash the Messenger of Allah (peace and blessings be upon him), the people differed about the manner of doing it. Some said: Shall we remove the clothes of the Messenger of Allah (peace and blessings be upon him) as we remove the clothes of our dead, or shall we wash him with his clothes on? Meanwhile, Allah cast such drowsiness upon them that the chin of every one of them dropped onto his chest (that is, they all fell asleep). Then an unseen caller called out from a corner of the house: Do you not know that the Messenger of Allah (peace and blessings be upon him) should be washed with his clothes on? So the Companions washed him in his shirt; they would pour water over him and rub his blessed body over the shirt. Sayyidah Aishah (may Allah be pleased with her) says: By Allah! Had I known beforehand what I came to know later (that is, this manner of washing), none but his wives would have washed the Messenger of Allah (peace and blessings be upon him). This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
