O men! serve your Lord Who created you and those before you so that you may guard (against evil). 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 about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. 23 But if you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 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 those who break God's covenant after they have pledged to keep it, and sever whatever God has ordered to be joined, and spread corruption in the land -- it is they who are the losers. 27 How disbelieve ye in Allah when ye were dead and He gave life to you! Then He will give you death, then life again, and then unto Him ye will return. 28 He it is who has created for you all that is on earth, and has applied His design to the heavens and fashioned them into seven heavens; and He alone has full knowledge of everything. 29
