O you who believe! spend (for the cause of Allâh) a portion of good and pure things, that you have yourselves earned and out of that which We have produced for you from the earth. Do not intend (upon spending) the bad and inferior. You would spend that (bad and inferior for the cause of Allâh) which you would not accept at all (for yourselves) unless you connive at it. And know that Allâh is Self-Sufficient, Ever Praiseworthy.
