۞ 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 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 Allah may reward them according to the best of their deeds, and add even more for them out of His Grace: for Allah doth provide for those whom He will, without measure. 38 And those who disbelieve - their works are like a mirage in a desert which the thirsty deemeth to be water, until when he cometh thereto he findeth not aught, and findeth Allah with himself, and He payeth him his account in full; and Allah is swift at reckoning. 39 Or like darkness in a wide, wide sea, waves surging upon waves, with clouds overhanging, darkness on darkness. If you stretch your hand, you could hardly see it. For him whom God does not give any light, there is no light. 40
