It is narrated from Hazrat Umm Zar (may Allah be pleased with her) that when the time of Hazrat Abu Zar’s (may Allah be pleased with him) death drew near, I began to weep. He asked, “Why are you weeping?” I said, “Why should I not weep? While you are dying in such a wilderness that I have no means to bury you, nor do I have enough cloth to shroud you.” He said, “Do not weep, and receive glad tidings, for I heard the Noble Prophet (peace and blessings be upon him) say: ‘Whoever dies among two or three Muslim children, and he bears their death with patience seeking reward, he will never see the fire of Hell.’ And I also heard the Noble Prophet (peace and blessings be upon him) say: ‘One of you will surely die in a wilderness, and a group of believers will be present with him.’ Now, each of those people has died in some city or among a group, and I am the one who is dying in the wilderness. By Allah, I am neither lying nor has a lie been told to me.”
