Musannaf Ibn Abi Shaybah

Mention was made to Ibrahim about giving ghusl (ritual washing) to a deceased person, so he said: In the same manner as a person in a state of janabah performs ghusl.

Hazrat Bakr says that I came to Madinah Tayyibah and asked about the bathing of the deceased. Some people said: Bathe the deceased just as a bride is bathed, except that saffron perfume should not be applied to him.
