O you have believed, do not void your donations with obliging (reproach) and hurt, as one who expends his wealth (for the sake) of showing off to mankind and does not believe in Allah and the Last Day. So, the likeness of him is as the likeness of a smooth rock on which is dust, then a shower hits (Literally: afflicts) it; so it leaves (the rock) solid. They are unable (to do) anything with whatever they have earned; and Allah does not guide the disbelieving people.
