O people, worship your Lord who has created you and those who have gone before you, so that you will be cautious. 21 Who made the earth a resting place for you and the heaven a canopy and (Who) sends down rain from the cloud, then brings forth with it subsistence for you of the fruits; therefore do not set up rivals to Allah while you 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 But unto those who have attained to faith and do good works give the glad tiding that theirs shall be gardens through which running waters flow. Whenever they are granted fruits therefrom as their appointed sustenance, they will say: "It is this that in days of yore was granted to us as our sustenance!" - for they shall be given something that will recall that [past]. And there shall they have spouses pure, and there shall they abide. 25 ۞ Behold, God does not disdain to propound a parable of a gnat, or of something [even] less than that. Now, as for those who have attained to faith, they know that it is the truth from their Sustainer - whereas those who are bent on denying the truth say: "What could God mean by this parable?" In this way does He cause many a one to go astray, just as He guides many a one aright: but none does He cause thereby to go astray save the iniquitous, 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 can you refuse to acknowledge God, seeing that you were lifeless and He gave you life, and that He will cause you to die and then will bring you again to life, whereupon unto Him you will be brought back? 28 It is He who created for you all that is in the earth, then He lifted Himself to heaven and levelled them seven heavens; and He has knowledge of everything. 29
