۞ 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 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 As for those who disbelieve, their deeds are like a mirage in the desert which the thirsty takes for water till he reaches it to find that there was nothing, and finds God with him who settles his account, for God is swift at the 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
