Chapter : Concerning the shrouding of the dead body.

Khabbab al-Aratt reported: We migrated with the Messenger of Allah (may peace be upon him) in the path of Allah seeking Allah’s pleasure alone. Thus our reward was assured with Allah. And amongst us were those who spent life (in such a state of piety and austerity) that nothing consumed their reward. Mus’ab b. ‘Umair was one of them. He was killed on the Day of Uhud, and nothing but a woollen cloak was found to shroud him. When we covered his head with it, his feet became uncovered, and when we covered his feet, his head was uncovered. Upon this the Messenger of Allah (may peace be upon him) said: Place it (this cloak) on the side of his head and cover his feet with grass. And there is one amongst us for whom the fruit is ripened and he enjoys it.
