Musannaf Ibn Abi Shaybah 39518 — What Abu Bakr (Ibn Abi Shaybah)

It is narrated from Sayyiduna Khabbab (may Allah be pleased with him): We migrated with the Messenger of Allah (peace and blessings be upon him), seeking the pleasure of Allah Almighty, so our reward became due upon Allah. Among us were some who did not consume anything of their reward. Among these is Sayyiduna Mus'ab bin Umayr (may Allah be pleased with him), who was martyred in the battle of Uhud, and nothing was available to shroud him except one sheet. When the Companions put this sheet over his head, his feet would be uncovered, and when they pulled it toward his feet, his blessed head would be uncovered. At this the Prophet (peace and blessings be upon him) said: "Put this sheet toward his head, and put idhkhir (a fragrant grass) on his feet." And among us were some whose fruits (of reward) ripened for them, so they are harvesting them.
