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 your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth). 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 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers. 24 And convey good news to those who believe and do good deeds, that they shall have gardens in which rivers flow; whenever they shall be given a portion of the fruit thereof, they shall say: This is what was given to us before; and they shall be given the like of it, and they shall have pure mates in them, and in them, they shall abide. 25 ۞ Allah disdains not to use the similitude of things, lowest as well as highest. Those who believe know that it is truth from their Lord; but those who reject Faith say: "What means Allah by this similitude?" By it He causes many to stray, and many He leads into the right path; but He causes not to stray, except those who forsake (the path),- 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 has created for you all that is on earth, and has applied His design to the heavens and fashioned them into seven heavens; and He alone has full knowledge of everything. 29
