O mankind! worship your Lord, Who hath created you and those before you, so that ye may ward off (evil). 21 Who has made the earth a bed for you and the sky a dome, and has sent down water from the sky to bring forth fruits for your provision. Do not knowingly set up rivals to Allah. 22 Should you have any doubt about what We have revealed to Our servant, present one chapter comparable to it and call all your supporters, besides God, if your claim is true. 23 But if you cannot do it, and you can never do it, then guard yourselves against the Fire whose fuel is men and stones, prepared for those who deny the truth. 24 But unto those who have attained to faith and do good works give the glad tiding that theirs shall be gardens through which running waters flow. Whenever they are granted fruits therefrom as their appointed sustenance, they will say: "It is this that in days of yore was granted to us as our sustenance!" - for they shall be given something that will recall that [past]. And there shall they have spouses pure, and there shall they abide. 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 can you disbelieve in God when you were dead [lifeless] and He gave you life? He will let you die once more, then bring you back to life again, whereupon you will be returned 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
