O men! serve your Lord Who created you and those before you so that you may guard (against evil). 21 The One Who has appointed the earth a base for you, and the sky a canopy – and caused water to pour down from the sky, thereby producing fruits as food for you; and do not knowingly set up rivals to Allah! 22 And if you are in doubt concerning that We have sent down on Our servant, then bring a sura like it, and call your witnesses, apart from God, if you are truthful. 23 And if ye do it not - and ye can never do it - then guard yourselves against the Fire prepared for disbelievers, whose fuel is of men and stones. 24 Give the good news to those who believe and do good works, that they will have Gardens through which rivers flow: whenever they are given fruit to eat they will say, "This is what we were provided with before," because they were given similar things. And there will be pure spouses for them, and they will abide there forever. 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 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 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
