O you who believe! Cancel not your charity by reminders of your generosity, or by injury— Like those who spend what they own to be seen of men, but believe neither in Allah nor in the Last Day. They are in the parable like a hard, barren rock, on which is a little soil; On it falls heavy rain which leaves it (just) a bare stone. They will be able to do nothing with the little they have earned. And Allah does not guide those who reject faith.
