‘Umarbin Khattab said: “I entered upon the Messenger of Allah (PBUH)whenhe was (sitting) on a reed mat. I sat down and (saw that) he waswearing a waist wrap, and there was no other barrier between him andthe mat but his waist wrap, and the reed mat had made marks on hisside. And I saw a handful of barley, nearly a Sa’, and some acacialeaves, in a corner of the room, and a skin hanging up. My eyesflowedwith tears, and he said: ‘Why are you weeping, O son ofKhattab?’ Isaid: ‘O Prophet of Allah, why should I not weep?This mat has mademarks on your side, and this is all you haveaccumulated, I cannot seeanything other than what I see (here),while Chosroes and Caesar liveamong fruits and rivers. You are theProphet of Allah and His ChosenOne, and this is what you haveaccumulated.’ He said: ‘O son ofKhattab, does it not please you(to know) that (these things) are forus in the Hereafter and forthem in this world?’ He said: ‘Yes.’” Translation Not Available
