O men! serve your Lord Who created you and those before you so that you may guard (against 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 If you are in doubt of what We have sent down to Our worshiper (Prophet Muhammad), produce a chapter comparable to it. Call upon your helpers, other than Allah, to assist you, if you are true. 23 But if you fail, as you are sure to fail, then guard yourselves against the Fire whose fuel is people and stones, prepared for the unbelievers. 24 And give glad tidings (O Muhammad) unto those who believe and do good works; that theirs are Gardens underneath which rivers flow; as often as they are regaled with food of the fruit thereof, they say: this is what was given us aforetime; and it is given to them in resemblance. There for them are pure companions; there for ever they abide. 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 Those who break Allah's Covenant after ratifying it, and sever what Allah has ordered to be joined (as regards Allah's Religion of Islamic Monotheism, and to practise its legal laws on the earth and also as regards keeping good relations with kith and kin), and do mischief on earth, it is they who are the losers. 27 What has made you disbelieve in Allah? Whereas you were dead and He gave you life; then He will give you death, then bring you to life again, and then it is to 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
