۞ Allah is the light of the heavens and the earth: His light (in the universe) may be likened (to the light of) a lamp in a niche: the lamp is in a glass shade: the glass shade is like a glittering star and lamp is lit with the olive oil of a blessed tree which is neither eastern nor western: its oil is (so fine) as if it were going to shine forth by itself though no fire touched it (as though all the means of increasing) light upon light (were provided); Allah guides to His light whomever He wills. He cites parables to make the Message clear to the people; He has perfect knowledge of everything. 35 [They worship] in the houses which God has allowed to be raised for the remembrance of His name, morning and evening, 36 are men who exalt Him there, whom neither trade nor sale can divert from the remembrance of Allah, and establish the prayers, and pay the obligatory charity; fearing a Day when hearts and eyes shall be turned about, 37 (They worship Him) so that God will reward their best deeds and give them more through His favors. God gives sustenance to whomever He wants without account. 38 But those who disbelieved - their deeds are like a mirage in a lowland which a thirsty one thinks is water until, when he comes to it, he finds it is nothing but finds Allah before Him, and He will pay him in full his due; and Allah is swift in account. 39 Or as darkness on a vast, abysmal sea. There covereth him a wave, above which is a wave, above which is a cloud. Layer upon layer of darkness. When he holdeth out his hand he scarce can see it. And he for whom Allah hath not appointed light, for him there is no light. 40
