۞ 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 Men whom neither trafficking nor bargaining diverteth from the remembrance of Allah and the establishment of the prayer and the giving of the poor-rate, fearing a Day whereon upset will be the hearts and sights. 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 As for the unbelievers, their works are like a mirage in the wilderness. The thirsty person thinks it is water, but when he comes near he finds that it is nothing. He finds Allah there, who pays him his account in full. Allah is Swift in reckoning. 39 Or it (the deeds of the unbelievers) are like the darkness of a deep, stormy sea with layers of giant waves, covered by dark clouds. It is darkness upon darkness whereby even if one stretches out his hands he can not see them. One can have no light unless God gives him light. 40
