O you who believe! do not make your charity worthless by reproach and injury, like him who spends his property to be seen of men and does not believe in Allah and the last day; so his parable is as the parable of a smooth rock with earth upon it, then a heavy rain falls upon it, so it leaves it bare; they shall not be able to gain anything of what they have earned; and Allah does not guide the unbelieving people.

And if anything (out of the dowries) of your wives has passed away from you to the unbelievers, then your turn comes, give to those whose wives have gone away the like of what they have spent, and be careful of (your duty to) Allah in Whom you believe.
