O you who believe! spend (benevolently) of the good things that you earn and or what We have brought forth for you out of the earth, and do not aim at what is bad that you may spend (in alms) of it, while you would not take it yourselves unless you have its price lowered, and know that Allah is Self-sufficient, Praiseworthy.

And as for the good land, its vegetation springs forth (abundantly) by the permission of its Lord, and (as for) that which is inferior (its herbage) comes forth but scantily; thus do We repeat the communications for a people who give thanks.
