Section : Shrouding the Dead.

Yahya related to me from Malik from Hisham ibn Urwa from his father from A'isha, the wife of the Prophet, may Allah bless him and grant him peace, that the Messenger of Allah, may Allah bless him and grant him peace, was shrouded in three pure white cotton garments, none of which was a long shirt or a turban.
