O mankind! worship your Lord, Who hath created you and those before you, so that ye may ward off (evil). 21 who made the earth a bed, and the sky a canopy; and it is He who sends down rain from above for the growth of every kind of food for your sustenance. And do not knowingly set up rivals to God. 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 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 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 ۞ Indeed Allah does not, for the sake of explanation, shy to illustrate an example of anything, whether it is of a gnat or something further (inferior) than it; so the believers know it is the Truth from their Lord; as for the disbelievers, they say, “What does Allah intend by such an example?” He misleads many thereby, and He guides many thereby; and with it He misleads only those who are rebellious. 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 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
