۞ 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 In houses which Allah has permitted to be exalted and that His name may be remembered in them; there glorify Him therein in the mornings and the evenings, 36 [Are] men whom neither commerce nor sale distracts from the remembrance of Allah and performance of prayer and giving of zakah. They fear a Day in which the hearts and eyes will [fearfully] turn about - 37 (And they behave like this) so that Allah may reward them for their excellent deeds and, in addition to it, show His favour to them out of His bounty: Allah provides without stint for anyone He pleases. 38 And (as for) those who disbelieve, their deeds are like the mirage in a desert, which the thirsty man deems to be water; until when he comes to it he finds it to be naught, and there he finds Allah, so He pays back to him his reckoning in full; and Allah is quick in reckoning; 39 Or [the state of a disbeliever] is like the darkness in a vast deep sea, overwhelmed with a great wave topped by a great wave, topped by dark clouds, darkness, one above another, if a man stretches out his hand, he can hardly see it! And he for whom Allah has not appointed light, for him there is no light. 40
