Narrated with this chain from Muhammad bin Ya'qub, from Ali bin Ibrahim, from his father, from Ibn Mahbub, from Ibn Sinan, from Aban bin Taghlib, who said: I heard Abu Abdillah عليه السلام, say: "The one who is killed in the way of Allah سبحانه وتعالى is buried in his clothes and is not washed, unless the Muslims find him while he still has some life in him and then he dies afterward. In that case, he is washed, shrouded, and embalmed. Indeed, the Messenger of Allah سبحانه وتعالى, peace be upon him and his family, shrouded Hamza عليه السلام in his clothes and did not wash him, but He صلى الله عليه وعلى آله وسلم prayed over him."
