O men! serve your Lord Who created you and those before you so that you may guard (against evil). 21 who has made the earth a resting-place for you and the sky a canopy, and has sent down water from the sky and thereby brought forth fruits for your sustenance: do not, then, claim that there is any power that could rival God, when you know [that He is One]. 22 If you are in doubt of what We have sent down to Our worshiper (Prophet Muhammad), produce a chapter comparable to it. Call upon your helpers, other than Allah, to assist you, if you are true. 23 And if ye do it not - and ye can never do it - then guard yourselves against the Fire prepared for disbelievers, whose fuel is of men and stones. 24 But give glad tidings to those who believe and work righteousness, that their portion is Gardens, beneath which rivers flow. Every time they are fed with fruits therefrom, they say: "Why, this is what we were fed with before," for they are given things in similitude; and they have therein companions pure (and holy); and they abide therein (for ever). 25 ۞ God is not loath to advance the similitude of a gnat or a being more contemptible; and those who believe know whatever is from the Lord is true. But those who disbelieve say: "What does God mean by this parable?" He causes some to err this way, and some He guides; yet He turns away none but those who transgress, 26 Who break the covenant of Allah after its confirmation and cut asunder what Allah has ordered to be joined, and make mischief in the land; these it is that are the losers. 27 How disbelieve ye in Allah when ye were dead and He gave life to you! Then He will give you death, then life again, and then unto Him ye will return. 28 He it is who created for you all that is on the earth, thereafter He turned to the heaven, and formed them seven heavens. And He is of everything the Knower. 29
