۞ God is the Light of the heavens and the earth. The parable of His light is, as it were, that of a niche containing a lamp; the lamp is [enclosed] in glass, the glass [shining] like a radiant star: [a lamp] lit from a blessed tree - an olive-tree that is neither of the east nor of the west the oil whereof [is so bright that it] would well-nigh give light [of itself] even though fire had not touched it: light upon light! God guides unto His light him that wills [to be guided]; and [to this end] God propounds parables unto men, since God [alone] has full knowledge of all things. 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 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 reward them for the best of their deeds, and bestow more on them of His bounty, for God gives whom He please without measure. 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 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
