۞ 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 as are not diverted by trade and merchandise from remembering Him and from establishing Salat and paying Zakat, for they fear the Day when the hearts will be overturned and the eyes will become petrified. 37 That Allah may recompense them the best for that which they worked and may increase unto them of His grace, and Allah provideth for whomsoever He will without measure. 38 And those who disbelieve - their works are like a mirage in a desert which the thirsty deemeth to be water, until when he cometh thereto he findeth not aught, and findeth Allah with himself, and He payeth him his account in full; and Allah is swift at 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
