۞ 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 (This niche) is in the houses that God has declared to be highly respected and His Name be mentioned therein in glory in the morning and evening 36 by people, who can neither be diverted by merchandise nor bargaining from worshipping God, saying their prayers and paying religious tax. They do these things, for they are afraid of the day when all hearts and eyes will undergo terrible unrest and crisis. 37 In order that Allah may reward them for their best deeds and by His munificence, bestow upon them an increased reward; and Allah gives sustenance to whomever He wills, without account. 38 But as for those who are bent on denying the truth, their [good] deeds are like a mirage in the desert, which the thirsty supposes to be water - until, when he approaches it, he finds that it was nothing: instead, he finds [that] God [has always been present] with him, and [that] He will pay him his account in full - for God is swift in reckoning! 39 Or like utter darkness in the deep sea: there covers it a wave above which is another wave, above which is a cloud, (layers of) utter darkness one above another; when he holds out his hand, he is almost unable to see it; and to whomsoever Allah does not give light, he has no light. 40
