O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 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 And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true. 23 But if you cannot do it, and you can never do it, then guard yourselves against the Fire whose fuel is men and stones, prepared for those who deny the truth. 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 ashamed to strike a similitude even of a gnat, or aught above it. As for the believers, they know it is the truth from their Lord; but as for unbelievers, they say, 'What did God desire by this for a similitude?' Thereby He leads many astray, and thereby He guides many; and thereby He leads none astray save the ungodly 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 can you disbelieve in God when you were dead [lifeless] and He gave you life? He will let you die once more, then bring you back to life again, whereupon you will be returned to Him. 28 He made for you all that lies within the earth, then turning to the firmament He proportioned several skies: He has knowledge of everything. 29
