O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 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 But if you do it not, and you can never do it, then fear the Fire (Hell) whose fuel is men and stones, prepared for the disbelievers. 24 And give glad tidings to those who believe and do righteous good deeds, that for them will be Gardens under which rivers flow (Paradise). Every time they will be provided with a fruit therefrom, they will say: "This is what we were provided with before," and they will be given things in resemblance (i.e. in the same form but different in taste) and they shall have therein Azwajun Mutahharatun (purified mates or wives), (having no menses, stools, urine, etc.) and they will abide therein forever. 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 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 do you disbelieve in God, seeing you were dead and He gave you life, then He shall make you dead, then He shall give you life, then unto Him you shall be returned? 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
