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 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 Give the good news to those who believe and do good works, that they will have Gardens through which rivers flow: whenever they are given fruit to eat they will say, "This is what we were provided with before," because they were given similar things. And there will be pure spouses for them, and they will abide there forever. 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 the covenant of Allah after contracting it and sever that which Allah has ordered to be joined and cause corruption on earth. It is those who are the losers. 27 How can you refuse to acknowledge God, seeing that you were lifeless and He gave you life, and that He will cause you to die and then will bring you again to life, whereupon unto Him you will be brought back? 28 He it is who has created for you all that is on earth, and has applied His design to the heavens and fashioned them into seven heavens; and He alone has full knowledge of everything. 29
