۞ 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 (mosques), which Allah has ordered to be raised (to be cleaned, and to be honoured), in them His Name is glorified in the mornings and in the afternoons or the evenings, 36 by people, who can neither be diverted by merchandise nor bargaining from worshipping God, saying their prayers and paying religious tax. They do these things, for they are afraid of the day when all hearts and eyes will undergo terrible unrest and crisis. 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 realms of darkness on a deep sea, which is covered by a wave, the wave covered by another wave, and above it is a cloud; layers of darkness upon darkness; if he removes his hand it does not seem visible; and the one to whom Allah does not provide light – there is no light for him anywhere. 40
