O ye who believe! make not your almsgiving vain by taunts and annoyance, like him who expends what he has for the sake of appearances before men, and believes not in God 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 nought with what they earn, for God guides not the misbelieving folk.
