O you who believe! do not take for intimate friends from among others than your own people; they do not fall short of inflicting loss upon you; they love what distresses you; vehement hatred has already appeared from out of their mouths, and what their breasts conceal is greater still; indeed, We have made the communications clear to you, if you will understand.

And remember when He made you successors after Ad and settled you in the land-- you make mansions on its plains and hew out houses in the mountains-- remember therefore Allah's benefits and do not act corruptly in the land, making mischief.
