O you men, serve your Lord Who created you, and those that were before you; haply so you will be godfearing; 21 Who has made the earth a bed for you and the sky a dome, and has sent down water from the sky to bring forth fruits for your provision. Do not knowingly set up rivals to Allah. 22 And if you be in doubt whether the Book We have sent down to Our Servant is from Us or not, then produce, at least, one Surah like this. You may call all your associates to assist you and avail yourselves of the help of any one other than Allah. If you are genuine in your doubt, do this. 23 And if you do not -- and you will not -- then fear the Fire, whose fuel is men and stones, prepared for 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 ۞ Lo! Allah disdaineth not to coin the similitude even of a gnat. Those who believe know that it is the truth from their Lord; but those who disbelieve say: What doth Allah wish (to teach) by such a similitude? He misleadeth many thereby, and He guideth many thereby; and He misleadeth thereby only miscreants; 26 who break their bond with God after it has been established [in their nature,] and cut asunder what God has bidden to be joined, and spread corruption on earth: these it is that shall be the losers. 27 How can you disbelieve in God when you were dead [lifeless] and He gave you life? He will let you die once more, then bring you back to life again, whereupon you will be returned to Him. 28 He it is Who created for you all that is in the earth, and He directed Himself to the heaven, so He made them complete seven heavens, and He knows all things. 29
