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 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 do not do this, and you can never do this, then fear the Fire which has been prepared for the disbelievers and which shall have men and stones for fuel. 24 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. 25 ۞ God does not disdain to give a parable about a gnat or a smaller creature. The faithful know that it is the truth from their Lord, but those who deny the truth ask, "What could God mean by this parable?" He lets many go astray through it, and guides many by it. But He makes only the disobedient go astray: 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 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 created for you all that is in the earth, then, He willed to the heaven, and leveled them seven heavens. He has knowledge of all things. 29
