He will say: Enter into fire among the nations that have passed away before you from among jinn and men; whenever a nation shall enter, it shall curse its sister, until when they have all come up with one another into it; the last of them shall say with regard to the foremost of them: Our Lord! these led us astray therefore give them a double chastisement of the fire. He will say: Every one shall have double but you do not know.

Allah is the light of the heavens and the earth; a likeness of His light is as a niche in which is a lamp, the lamp is in a glass, (and) the glass is as it were a brightly shining star, lit from a blessed olive-tree, neither eastern nor western, the oil whereof almost gives light though fire touch it not-- light upon light-- Allah guides to His light whom He pleases, and Allah sets forth parables for men, and Allah is Cognizant of all things.
