Khabab reported,

We migrated with the Messenger of Allah ﷺ seeking the pleasure of Allah, and our reward became due upon Allah. Among us were those who passed on without taking anything of their reward in this world. One of them was Musab bin Umayr, who was killed on the day of Uhud. We could find nothing to shroud him in except a striped woolen cloak. When we covered his head with it, his feet were exposed, and when we covered his feet, his head was exposed. So the Messenger of Allah ﷺ instructed us to cover his head with it and place idhkhir grass over his feet. And among us were those whose fruit had ripened, and they were harvesting it.

خباب قال

هاجرنا مع رسول الله ﷺ نبتغي وجه الله ووجب أجرنا على الله فمنا من مضى لم يأكل من أجره شيئا منهم مصعب بن عمير قتل يوم أحد فلم نجد شيئا نكفنه فيه إلا نمرة كنا إذا غطينا بها رأسه خرجت رجلاه فإذا غطينا رجليه خرج رأسه فأمرنا رسول الله ﷺ أن نغطي رأسه بها ونجعل على رجليه من إذخر ومنا من أينعت له ثمرته فهو يهدبها
