Narrated Abu Huraira:
Allah's Apostle said, "Allah says, "If My slave intends to do a bad deed then (O Angels) do not write it unless he does it; if he does it, then write it as it is, but if he refrains from doing it for My Sake, then write it as a good deed (in his account). (On the other hand) if he intends to go a good deed, but does not do it, then write a good deed (in his account), and if he does it, then write it for him (in his account) as ten good deeds up to seven-hundred times.'
