Abdullah bin Ata'a عبد الله بن عطاء الطائفي · Wills (Kitab Al-Wasaya)

Mus'ab b. 'Umar was killed at the battle of Uhud, and for him only a coarse cloth would be found as shroud. When we covered his head, his feet showed, and when we covered his feet, his head showed. So the Messenger of Allah (ﷺ) said: Cover his head with it (cloth), and put some rushes over his feet.
