Sahih Bukhari

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 makes you die and then bring you to life again."" He said, ""If Allah should make me die and then resurrect me, 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?
