O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who has made the earth a bed for you and the sky a dome, and has sent down water from the sky to bring forth fruits for your provision. Do not knowingly set up rivals to Allah. 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 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 to those who believe and do good deeds; that for them are Gardens beneath which rivers flow; when they are provided with a fruit of the Gardens, they will say, “This is the same food as what was given to us before” whereas it is in resemblance; and in the Gardens are pure spouses for them; and they shall abide in it forever. 25 ۞ God is not ashamed to strike a similitude even of a gnat, or aught above it. As for the believers, they know it is the truth from their Lord; but as for unbelievers, they say, 'What did God desire by this for a similitude?' Thereby He leads many astray, and thereby He guides many; and thereby He leads none astray save the ungodly 26 Those who break the covenant of Allah after ratifying it, and sever that which Allah ordered to be joined, and (who) make mischief in the earth: Those are they who 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 it is Who created for you all that is in the earth, and He directed Himself to the heaven, so He made them complete seven heavens, and He knows all things. 29
