O mankind, worship your Lord, who created you and those before you, that you may become righteous - 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 And if you doubt any part of what We have bestowed from on high, step by step, upon Our servant [Muhammad,] then produce a surah of similar merit, and call upon any other than God to bear witness for you if what you say is true! 23 If you do not produce such a chapter and you never will then guard yourselves against the fire whose fuel will be people and stones and is prepared for those who hide the Truth. 24 And bear thou the glad tidings unto those who believe and do righteous works that verily for them shall be Gardens whereunder rivers flow. So oft as they shall be provided with a fruit therefrom they will say: this is that wherewith we were provided afore; and they shall be vouchsafed that which is consimilar; and for them shall be therein spouses purified, and therein they shall be abiders. 25 ۞ God does not disdain to give a parable about a gnat or a smaller creature. The faithful know that it is the truth from their Lord, but those who deny the truth ask, "What could God mean by this parable?" He lets many go astray through it, and guides many by it. But He makes only the disobedient go astray: 26 Who break the covenant of Allah after contracting it and sever that which Allah has ordered to be joined and cause corruption on earth. It is those who 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 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
