O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. 22 And if you are in doubt concerning that We have sent down on Our servant, then bring a sura like it, and call your witnesses, apart from God, if you are truthful. 23 If you do not produce such a chapter and you never will then guard yourselves against the fire whose fuel will be people and stones and is prepared for those who hide the Truth. 24 And give glad tidings (O Muhammad) unto those who believe and do good works; that theirs are Gardens underneath which rivers flow; as often as they are regaled with food of the fruit thereof, they say: this is what was given us aforetime; and it is given to them in resemblance. There for them are pure companions; there for ever 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 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 How can you disbelieve in Allah when you were lifeless and He brought you to life; then He will cause you to die, then He will bring you [back] to life, and then to Him you will be returned. 28 It is He who created for you all of that which is on the earth. Then He directed Himself to the heaven, [His being above all creation], and made them seven heavens, and He is Knowing of all things. 29
