O mankind! worship your Lord, Who hath created you and those before you, so that ye may ward off (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 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. 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 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 ۞ God is not ashamed to strike a similitude even of a gnat, or aught above it. As for the believers, they know it is the truth from their Lord; but as for unbelievers, they say, 'What did God desire by this for a similitude?' Thereby He leads many astray, and thereby He guides many; and thereby He leads none astray save the ungodly 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 can you disbelieve in Allah? Seeing that you were dead and He gave you life. Then He will give you death, then again will bring you to life (on the Day of Resurrection) and then unto Him you will return. 28 He it is who created for you all that is on the earth, thereafter He turned to the heaven, and formed them seven heavens. And He is of everything the Knower. 29
