۞ 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 (On the other hand,) the deeds of those who disbelieved, maybe likened to a mirage in a waterless desert, which the thirsty one took for water; but when he reached there he found nothing to drink; nay, he found there Allah Who settled his full account, and Allah is very swift at reckoning. 39 Or [else, their deeds are] like the depths of darkness upon an abysmal sea, made yet more dark by wave billowing over wave, with [black] clouds above it all: depths of darkness, layer upon layer, [so that] when one holds up his hand, he can hardly see it: for he to whom God gives no light, no light whatever has he! 40
