O people, worship your Lord who has created you and those who have gone before you, so that you will be cautious. 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 you be in doubt whether the Book We have sent down to Our Servant is from Us or not, then produce, at least, one Surah like this. You may call all your associates to assist you and avail yourselves of the help of any one other than Allah. If you are genuine in your doubt, do this. 23 But if you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 24 And give glad tidings (O Muhammad) unto those who believe and do good works; that theirs are Gardens underneath which rivers flow; as often as they are regaled with food of the fruit thereof, they say: this is what was given us aforetime; and it is given to them in resemblance. There for them are pure companions; there for ever they abide. 25 ۞ Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors, 26 those who break God's covenant after they have pledged to keep it, and sever whatever God has ordered to be joined, and spread corruption in the land -- it is they who are the losers. 27 Then how can you disbelieve in God? He gave you life when you were dead. He will make you die again then bring you back to life: To Him then you will return. 28 It is He who created everything on the earth for you: then He turned towards heaven and fashioned it into the seven heavens. He has knowledge of all things. 29
