O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 who assigned to you the earth for a couch, and heaven for an edifice, and sent down out of heaven water, wherewith He brought forth fruits for your provision; so set not up compeers to God wittingly. 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 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 good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. 25 ۞ God does not hesitate to set forth parables of anything even a gnat. The believers know that it is the truth from their Lord, but those who deny the truth say, "What does God mean by such parables?" In fact, by such parables God misleads and guides many. However, He only misleads the evil doers 26 who break Allah's covenant after ratifying it; who cut asunder what Allah has ordered to be joined, and who produce chaos on the Earth. These are the people who are indeed 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 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
