O mankind! worship your Lord, Who hath created you and those before you, so that ye may ward off (evil). 21 who has made the earth a resting-place for you and the sky a canopy, and has sent down water from the sky and thereby brought forth fruits for your sustenance: do not, then, claim that there is any power that could rival God, when you know [that He is One]. 22 If you are in doubt about the revelation We have sent down to Our servant, then produce a single chapter like it, and call upon your helpers besides God, if you are truthful. 23 If you do not produce such a chapter and you never will then guard yourselves against the fire whose fuel will be people and stones and is prepared for those who hide the Truth. 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 ۞ Verily Allah is not ashamed to propound a similitude, be it of a gnat or of aught above it. Then as to those who believe, they know that it is the truth from their Lord. And to those who disbelieve, they say what intendeth God by similitude? He sendeth many astray thereby, and He guideth many thereby, and He sendeth not astray thereby any except the transgressors, 26 Who break the covenant of Allah after contracting it and sever that which Allah has ordered to be joined and cause corruption on earth. It is those who 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 has created for you all that is on earth, and has applied His design to the heavens and fashioned them into seven heavens; and He alone has full knowledge of everything. 29
