O mankind! Worship your Lord, Who has created you and those before you, in the hope of attaining piety. 21 Who hath made the earth for you a carpet and the heaven a structure, and sent down from heaven water, and brought forth therewith fruits as a Provision for you; wherefore set not up compeers unto Allah while ye know. 22 And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true. 23 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers. 24 But give glad tidings to those who believe and work righteousness, that their portion is Gardens, beneath which rivers flow. Every time they are fed with fruits therefrom, they say: "Why, this is what we were fed with before," for they are given things in similitude; and they have therein companions pure (and holy); and they abide therein (for ever). 25 ۞ Behold, God does not disdain to propound a parable of a gnat, or of something [even] less than that. Now, as for those who have attained to faith, they know that it is the truth from their Sustainer - whereas those who are bent on denying the truth say: "What could God mean by this parable?" In this way does He cause many a one to go astray, just as He guides many a one aright: but none does He cause thereby to go astray save the iniquitous, 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 will ye disbelieve in Allah whereas ye were lifeless and he quickened you; thereafter He will cause you to die, thereafter He will give you life, thereafter unto Him ye shall be returned! 28 It is He Who hath created for you all things that are on earth; Moreover His design comprehended the heavens, for He gave order and perfection to the seven firmaments; and of all things He hath perfect knowledge. 29
