An-Nur · 24:39

39. There is no reward for the deeds of those who disbelieve in Allah; it is like a mirage that a thirsty person sees on a low-lying piece of land and assumes it to be water. He walks towards it, until when he reaches it, does not find any water. Likewise is a disbeliever: he thinks his deeds shall benefit him, until he dies and is resurrected, but does not find their reward. Rather, he finds his Lord in front of him who takes him to account fully for his deeds; and Allah is swift in taking account.
