Hiring

Narrated Khabbab (Radi-Allahu 'anhu):

I was a blacksmith and did some work for Al-'As bin Wail. When he owed me
some money for my work, I went to him to ask for that amount. He said, "I
will not pay you unless you disbelieve in Muhammad." I said, "By Allah! I
will never do that till you die and be resurrected." He said, "Will I be
dead and then resurrected after my death?" I said, "Yes." He said, "There I
will have property and offspring and then I will pay you your due." Then
Allah revealed. 'Have you seen him who disbelieved in Our signs, and yet
says: I will be given property and offspring?' (19.77)
