Narrated Khabbab: I was a blacksmith in Mecca Once I made a sword for Al-`Asi bin Wail As-Sahmi. When I went to demand its price, he said, I will not give it to you till you disbelieve in Muhammad. I said, I shall not disbelieve in Muhammad till Allah make you die and then bring you to life again. He said, If Allah should make me die and then resurrect me and I would have wealth and children. So Allah revealed:-- 'Have you seen him who disbelieved in Our Signs, and (yet) says I shall certainly be given wealth and children? Has he known the unseen or has he taken a covenant from (Allah) the Beneficent?' (19.77- 78)
