Narrated by Masruq Khabbab said, "During the pre-lslamic period, I was a blacksmith and Al-Asi bin Wail owed me a debt." So Khabbab went to him to demand the debt. He said, "I will not give you (your due) till you disbelieve in Muhammad." Khabbab said, "By Allah, I shall not disbelieve in Muhammad till Allah makes you die and then resurrects you." Al-Asi said, "So leave me till I die and then be resurrected, for I will be given wealth and children whereupon I will pay you your debt." So this Verse was revealed: 'Have you seen him who disbelieved in Our Signs and, (yet) says: I shall certainly be given wealth and children.' (19.77)
