People, worship your Lord who created you and those who lived before you, so that you may become pious. 21 Worship God who has rendered the earth as a floor for you and the sky as a dome for you and has sent water down from the sky to produce fruits for your sustenance. Do not knowingly set up anything as an equal to God. 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 And if you cannot do it - and most certainly you cannot do it - then be conscious of the fire whose fuel is human beings and stones which awaits all who deny the truth! 24 And give glad tidings to those who believe and do good deeds; that for them are Gardens beneath which rivers flow; when they are provided with a fruit of the Gardens, they will say, “This is the same food as what was given to us before” whereas it is in resemblance; and in the Gardens are pure spouses for them; and they shall abide in it forever. 25 ۞ Verily Allah is not ashamed to propound a similitude, be it of a gnat or of aught above it. Then as to those who believe, they know that it is the truth from their Lord. And to those who disbelieve, they say what intendeth God by similitude? He sendeth many astray thereby, and He guideth many thereby, and He sendeth not astray thereby any except the transgressors, 26 who break the covenant of Allah after accepting it and sever what Allah has bidden to be joined and corrupt in the land. These are the losers. 27 How will ye disbelieve in Allah whereas ye were lifeless and he quickened you; thereafter He will cause you to die, thereafter He will give you life, thereafter unto Him ye shall be returned! 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
