O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 Who hath appointed the earth a resting-place for you, and the sky a canopy; and causeth water to pour down from the sky, thereby producing fruits as food for you. And do not set up rivals to Allah when ye know (better). 22 If you are in doubt of what We have revealed to Our votary, then bring a Surah like this, and call any witness, apart from God, you like, 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 to those who believe and do righteous good deeds, that for them will be Gardens under which rivers flow (Paradise). Every time they will be provided with a fruit therefrom, they will say: "This is what we were provided with before," and they will be given things in resemblance (i.e. in the same form but different in taste) and they shall have therein Azwajun Mutahharatun (purified mates or wives), (having no menses, stools, urine, etc.) and they will abide therein forever. 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 such as break the covenant of God after its solemn binding, and such as cut what God has commanded should be joined, and such as do corruption in the land -- they shall be the losers. 27 How do you disbelieve in God, seeing you were dead and He gave you life, then He shall make you dead, then He shall give you life, then unto Him you shall be returned? 28 He made for you all that lies within the earth, then turning to the firmament He proportioned several skies: He has knowledge of everything. 29
