O you who believe! Make not your almsgiving vain by reproach (or reminders of your generosity) and injury, like him who expends what he has for the sake of appearances before men, and believes not in Allah and the Last Day; for his likeness is as the likeness of a flint with soil upon it, and a heavy shower falls on it and leaves it bare rock; they can do naught with what they earn, for Allah guides not the misbelieving folk.
