O men! serve your Lord Who created you and those before you so that you may guard (against evil). 21 who made the earth a bed, and the sky a canopy; and it is He who sends down rain from above for the growth of every kind of food for your sustenance. And do not knowingly set up rivals to God. 22 If you are in doubt about the revelation We have sent down to Our servant, then produce a single chapter like it, and call upon your helpers besides God, if you are truthful. 23 And if you do not -- and you will not -- then fear the Fire, whose fuel is men and stones, prepared for 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 ۞ God is not loath to advance the similitude of a gnat or a being more contemptible; and those who believe know whatever is from the Lord is true. But those who disbelieve say: "What does God mean by this parable?" He causes some to err this way, and some He guides; yet He turns away none but those who transgress, 26 who break their bond with God after it has been established [in their nature,] and cut asunder what God has bidden to be joined, and spread corruption on earth: these it is that shall be the losers. 27 How dare you deny the existence of God Who gave you life when you initially had no life. He will cause you to die and bring you to life again. Then you will return to His Presence. 28 He it is Who created for you all that is in the earth, and He directed Himself to the heaven, so He made them complete seven heavens, and He knows all things. 29
