O mankind! worship your Lord, Who hath created you and those before you, so that ye may ward off (evil). 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 If you are in doubt of what We have revealed to Our votary, then bring a Surah like this, and call any witness, apart from God, you like, if you are truthful. 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 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 ۞ 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 the covenant of Allah after accepting it and sever what Allah has bidden to be joined and corrupt in the land. These are the losers. 27 How dare you deny the existence of God Who gave you life when you initially had no life. He will cause you to die and bring you to life again. Then you will return to His Presence. 28 He made for you all that lies within the earth, then turning to the firmament He proportioned several skies: He has knowledge of everything. 29
