People, worship your Lord, who created you and those before you, so that you may become righteous, 21 who made the earth a bed, and the sky a canopy; and it is He who sends down rain from above for the growth of every kind of food for your sustenance. And do not knowingly set up rivals to God. 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 But if you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 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 such as break the covenant of God after its solemn binding, and such as cut what God has commanded should be joined, and such as do corruption in the land -- they shall be 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 It is He Who hath created for you all things that are on earth; Moreover His design comprehended the heavens, for He gave order and perfection to the seven firmaments; and of all things He hath perfect knowledge. 29
