۞ 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 (The light is lit) in houses of worship which God has allowed to be raised, and His name remembered in them. His praises are sung there morning and evening, 36 people who are not distracted by trade or commerce from the remembrance of God and the observance of prayer and the payment of the zakat -- fearing a Day when 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 But the Unbelievers,- their deeds are like a mirage in sandy deserts, which the man parched with thirst mistakes for water; until when he comes up to it, he finds it to be nothing: But he finds Allah (ever) with him, and Allah will pay him his account: and Allah is swift in taking account. 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
