۞ 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 people whom neither [worldly] commerce nor striving after gain can divert from the remembrance of God, and from constancy in prayer, and from charity: [people] who are filled with fear [at the thought] of the Day on which all hearts and eyes will be convulsed, 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 the unbelievers, their works are as a mirage in a spacious plain which the man athirst supposes to be water, till, when he comes to it, he finds it is nothing; there indeed he finds God, and He pays him his account in full; (and God is swift at the reckoning.) 39 Or like darkness on a deep ocean covered by waves billowing over waves and overcast with clouds: darkness upon darkness. If he stretches out his hand, he can scarcely see it. Indeed, the man from whom God withholds His light shall find no light at all. 40
