O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who hath made the earth for you a carpet and the heaven a structure, and sent down from heaven water, and brought forth therewith fruits as a Provision for you; wherefore set not up compeers unto Allah while ye know. 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 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 ۞ Allah is not shy to strike a parable whatsoever a gnat or larger. Those who believe know that it is the truth from their Lord. As for those who disbelieve they ask: 'What could Allah mean by this parable? By it, Allah misleads many and guides many.' But He misleads none except the evildoers, 26 Who break the covenant of Allah after the ratification thereof, and sunder that which Allah hath commanded should be joined, and act corruptly on the earth. These! they are 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
