Tell them (O Prophet): “O you servants of Mine who believe, have fear of your Lord. A good end awaits those who did good in this world. Allah's earth is spacious. Verily those who persevere shall be granted their reward beyond all reckoning.” 10 Say [O Muhammad]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say, "It is God I serve, sincere in my faith in Him alone -- 14 and [it is up to you, O sinners, to] worship whatever you please instead of Him!" Say: "Behold, the [true] losers will be they who shall have lost their own selves and their kith and kin on Resurrection Day: for is not this, this, the [most] obvious loss? 15 There shall be sheets of fire above them and beneath them. This is the end against which Allah warns His servants. So dread My wrath, O you servants of Mine!” 16 There is good news for those who shun the worship of false deities and turn to God, so give good news to My servants, 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of understanding. 18 Can he against whom the sentence of punishment has been justified (be rescued)? Can you save him who is in the Fire? 19 But those who fear Allah and keep their duty to their Lord (Allah), for them are built lofty rooms; one above another under which rivers flow (i.e. Paradise). (This is) the Promise of Allah: and Allah does not fail in (His) Promise. 20 Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding. 21
