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 for you, the sky a canopy, and sends forth rain from the skies that fruits may grow -- your food and sustenance. So, do not make another the equal of God knowingly. 22 And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true. 23 But if you cannot, as indeed you cannot, then guard yourselves against the Fire whose fuel is men and rocks, which has been prepared for the infidels. 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 ۞ God does not hesitate to set forth parables of anything even a gnat. The believers know that it is the truth from their Lord, but those who deny the truth say, "What does God mean by such parables?" In fact, by such parables God misleads and guides many. However, He only misleads the evil doers 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 What has made you disbelieve in Allah? Whereas you were dead and He gave you life; then He will give you death, then bring you to life again, and then it is to Him you 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
