Abu Dawud Book 14, Hadith Number 3135.

Chapter : Not known.

Narated By ‘Aisha, Ummul Mu’minin : By Allah, we did not know whether we should take off the clothes of the Apostle of Allah (PBUH) as we took off the clothes of our dead, or wash him while his clothes were on him. When they (the people) differed among themselves, Allah cast slumber over them until every one of them had put his chin on his chest.

Then a speaker spoke from a side of the house, and they did not know who he was: Wash the Prophet (PBUH) while his clothes are on him. So they stood round the Prophet (PBUH) and washed him while he had his shirt on him. They poured water on his shirt, and rubbed him with his shirt and not with their hands. ‘Aisha used to say: If I had known beforehand about my affair what I found out later, none would have washed him except his wives.
