O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 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 ye are in doubt concerning that which We reveal unto Our slave (Muhammad), then produce a surah of the like thereof, and call your witness beside Allah if ye 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 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 such as break the covenant of God after its solemn binding, and such as cut what God has commanded should be joined, and such as do corruption in the land -- they shall be 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
