O mankind, worship your Lord, who created you and those before you, that you may become righteous - 21 who assigned to you the earth for a couch, and heaven for an edifice, and sent down out of heaven water, wherewith He brought forth fruits for your provision; so set not up compeers to God wittingly. 22 And if you are in doubt as to that which We have revealed to Our servant, then produce a chapter like it and call on your witnesses besides Allah 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 (Muhammad), tell the righteously striving believers of the happy news, that for them there are gardens wherein streams flow. Whenever they get any fruit from the gardens as food, they will say, "This is just what we had before (we came here). These fruits are produced very much like them (those we had before)." They will have purified spouses and it is they who will live 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 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 is it that you adopt the attitude of disbelief towards Allah when the fact is that you were lifeless and He gave you life, and He will take away life from you and will again restore you to life: then you shall ultimately return to Him. 28 He it is Who created for you all that is in the earth, and He directed Himself to the heaven, so He made them complete seven heavens, and He knows all things. 29
