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: 'I am ordered to worship Allah making my religion sincerely His. 11 and I have been commanded to be the first of those that surrender.' 12 Say: "If I disobey my Lord, I fear the punishment of an evil Day." 13 Say, "Allah [alone] do I worship, sincere to Him in my religion, 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 They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore fear Me!" 16 And (as for) those who keep off from the worship of the idols and turn to Allah, they shall have good news, therefore give good news to My servants, 17 (Muhammad), give the glad news to those of Our servants who listen to the words and only follow the best ones. Tell them that they are those whom God has guided. They are the people of understanding. 18 He against whom the word of chastisement is realized -- shalt thou deliver him out of the Fire? 19 As for those who fear their Lord, there await high mansions above which are built (more) high mansions, beneath which rivers flow, such is the promise of Allah; Allah will not fail His promise. 20 Beholdest thou not that Allah sendeth down water from the heaven, and causeth it to enter springs in the earth, and thereafter produceth thereby corn various coloured. Thereafter it wirhereth, and thou beholdest it turn yellow; then He maketh it chaff. Verily herein is an admonition for men of understanding. 21
