O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 21 Who hath appointed the earth a resting-place for you, and the sky a canopy; and causeth water to pour down from the sky, thereby producing fruits as food for you. And do not set up rivals to Allah when ye know (better). 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 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 ۞ Well, Allah is not ashamed to cite the similitude of a gnat or of something even more insignificant than this. As for those who believe, they come to know from the same similitude that it is the Revelation from their Lord; but those who disbelieve, say, "What does Allah mean by such similitudes?" Allah leads astray many and guides many to the right way by the same thing. And He leads astray only those who disobey Allah; 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 do you deny Allah and you were dead and He gave you life? Again He will cause you to die and again bring you to life; then you shall be brought back to Him. 28 He it is Who created for you all that there is on the Earth; He then turned to the sky and ordered it into seven heavens. And He has full knowledge of everything. 29
