O men! serve your Lord Who created you and those before you so that you may guard (against evil). 21 It is He Who has made the earth a bed for you and the sky a canopy; and it is He Who sends down rain from above for the growth of every kind of food products for your sustenance. So, when you know this, you should not set up equals to rank with Allah. 22 And if you (Arab pagans, Jews, and Christians) are in doubt concerning that which We have sent down (i.e. the Quran) to Our slave (Muhammad Peace be upon him), then produce a Surah (chapter) of the like thereof and call your witnesses (supporters and helpers) besides Allah, if you are truthful. 23 And if you do not -- and you will not -- then fear the Fire, whose fuel is men and stones, prepared for unbelievers. 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 ۞ 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 Those who break the covenant of Allah after ratifying it, and sever that which Allah ordered to be joined, and (who) make mischief in the earth: Those are they who are 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 It is He who created for you all that is in the earth, then He lifted Himself to heaven and levelled them seven heavens; and He has knowledge of everything. 29
