So, O you people, adore your Lord who created you, as He did those before you, that you could take heed for yourselves and fear Him 21 Who has made the earth a resting place for you, and the sky as a canopy, and sent down water (rain) from the sky and brought forth therewith fruits as a provision for you. Then do not set up rivals unto Allah (in worship) while you know (that He Alone has the right to be worshipped). 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 cannot do it - and most certainly you cannot do it - then be conscious of the fire whose fuel is human beings and stones which awaits all who deny the truth! 24 And give good news (O Muhammad), to those who believe in this Book and do good deeds (in accordance with its teachings). For them there will be gardens underneath which canals flow. Their fruits will so resemble the fruits on the Earth that every time they will be provided with fruits, they will say, "Such fruits were provided to us before on the Earth. " And there will be pure spouses for them and therein they will live 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 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 can you disbelieve in Allah when you were lifeless and He brought you to life; then He will cause you to die, then He will bring you [back] to life, and then to Him you will 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
