Ali bin Abu Talib reported,

I washed the Prophet ﷺ, then I looked closely to see if anything appeared from the deceased as it usually does, but I saw nothing. He was fragrant, both in life and in death.Four people undertook his burial and interment apart from the rest, Ali, Abbas, Fadl, and Salih the freed slave of the Messenger of Allah ﷺ. A lahd grave was dug for the Messenger of Allah ﷺ, and bricks were set up over him.

عن علي بن أبي طالب قال

غسلت النبي ﷺ فذهبت لأنظر ما يكون من الميت، فلم أر شيئا، وكان طيبا حيا وميتا، وولي دفنه و إجنانه دون الناس أربعة: علي والعباس والفضل وصالح مولى رسول الله ﷺ، و الحد الرسول الله ﷺ، الحدا، ونصب عليه اللبن نصبا.
