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