۞ Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within glass, the glass as if it were a pearly [white] star lit from [the oil of] a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire. Light upon light. Allah guides to His light whom He wills. And Allah presents examples for the people, and Allah is Knowing of all things. 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 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 that God may recompense them for their fairest works and give them increase of His bounty; and God provides whomsoever He will, without reckoning. 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
