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 If you are in doubt about the revelation We have sent down to Our servant, then produce a single chapter like it, and call upon your helpers besides God, 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 glad tidings to those who believe and do good deeds; that for them are Gardens beneath which rivers flow; when they are provided with a fruit of the Gardens, they will say, “This is the same food as what was given to us before” whereas it is in resemblance; and in the Gardens are pure spouses for them; and they shall abide in it forever. 25 ۞ God is not ashamed to strike a similitude even of a gnat, or aught above it. As for the believers, they know it is the truth from their Lord; but as for unbelievers, they say, 'What did God desire by this for a similitude?' Thereby He leads many astray, and thereby He guides many; and thereby He leads none astray save the ungodly 26 who break their established covenant with Him and the relations He has commanded to be kept and who spread evil in the land. These are the ones who lose a great deal. 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 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
