Narrated Khabbab:
I was a blacksmith In the Pre-lslamic period of ignorance, and 'Asi bin Wail owed me some money. I went to him to demand it, but he said to me, "I will not pay you unless you reject faith in Muhammad." I replied, "By Allah, I will never disbelieve Muhammad till Allah let you die and then resurrect you." He said, "Then wait till I die and come to life again, for then I will be given property and offspring and will pay your right." So, thus revelation came: "Have you seen him who disbelieved in Our signs and yet says, 'I will be given property and offspring?' " (19.77)
