Yahya related to me from Yahya ibn Said that Umar ibn al-Khattab asked a man what his name was. He said, "Jamra (live coal)." "The son of who?" He said, "Ibn Shihab (meteor, flame)." "From whom?" He said, "From al-Huraqa (burning)." "Where do you live?" He said, "At Harrat an-Nar (lava field of the fire). "At which one of them?" He said, "At Dhati Ladha (one with flames)." Umar said, "Go and look at your family - they have been burned." Yahya added, "It was as Umar ibn al-Khattab, may Allah be pleased with him, said."
