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 ye are in doubt concerning that which We reveal unto Our slave (Muhammad), then produce a surah of the like thereof, and call your witness beside Allah if ye are truthful. 23 And if you are unable to bring forth (one chapter) – and We declare that you can never bring one – then fear the fire (of hell), the fuel of which is men and stones; kept ready for the disbelievers. 24 Bear glad tidings to those who believe and do good works. They shall live in Gardens underneath which rivers flow. Whenever they are given fruit as provision they will say: 'This is what we were given before,' for they shall be given in resemblance. Therein they shall have pure spouses, and shall live there for ever. 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 who break their established covenant with Him and the relations He has commanded to be kept and who spread evil in the land. These are the ones who lose a great deal. 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 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
