O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth). 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 But if you cannot do it, and you can never do it, then guard yourselves against the Fire whose fuel is men and stones, prepared for those who deny 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 ۞ 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 its confirmation and cut asunder what Allah has ordered to be joined, and make mischief in the land; these it is that are the losers. 27 How do you disbelieve in God, seeing you were dead and He gave you life, then He shall make you dead, then He shall give you life, then unto Him you shall be returned? 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
