O people, worship your Lord who has created you and those who have gone before you, so that you will be cautious. 21 Who hath made the earth for you a carpet and the heaven a structure, and sent down from heaven water, and brought forth therewith fruits as a Provision for you; wherefore set not up compeers unto Allah while ye know. 22 And if you doubt any part of what We have bestowed from on high, step by step, upon Our servant [Muhammad,] then produce a surah of similar merit, and call upon any other than God to bear witness for you if what you say is true! 23 But if you fail, as you are sure to fail, then guard yourselves against the Fire whose fuel is people and stones, prepared for the unbelievers. 24 And bear thou the glad tidings unto those who believe and do righteous works that verily for them shall be Gardens whereunder rivers flow. So oft as they shall be provided with a fruit therefrom they will say: this is that wherewith we were provided afore; and they shall be vouchsafed that which is consimilar; and for them shall be therein spouses purified, and therein they shall be abiders. 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 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 What has made you disbelieve in Allah? Whereas you were dead and He gave you life; then He will give you death, then bring you to life again, and then it is to Him you will return! 28 He it is who created for you all that is on the earth, thereafter He turned to the heaven, and formed them seven heavens. And He is of everything the Knower. 29
