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, and the sky a canopy; and it is He who sends down rain from above for the growth of every kind of food for your sustenance. And do not knowingly set up rivals to God. 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 And if ye do it not - and ye can never do it - then guard yourselves against the Fire prepared for disbelievers, whose fuel is of men and stones. 24 And convey good news to those who believe and do good deeds, that they shall have gardens in which rivers flow; whenever they shall be given a portion of the fruit thereof, they shall say: This is what was given to us before; and they shall be given the like of it, and they shall have pure mates in them, and in them, they shall abide. 25 ۞ Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors, 26 who break Allah's covenant after ratifying it; who cut asunder what Allah has ordered to be joined, and who produce chaos on the Earth. These are the people who are indeed 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
