Tell them: "O my creatures who have come to belief, have fear of displeasing your Lord. There is good for those who do good in this world, and productive is God's earth. Only those who persevere will get their reward measureless." 10 Say: 'I am ordered to worship Allah making my religion sincerely His. 11 "And I am commanded to be the first of those who bow to Allah in Islam." 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say: Allah I worship, making my religion pure for Him (only). 14 Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be the manifest loss! 15 Above them are mountains of fire and beneath them are mountains of fire; Allah scares His bondmen with this; “O My bondmen! Fear Me!” 16 There are happy tidings for those who keep away from the worship of false gods and turn to God in repentance. Give glad tidings to My creatures. 17 Those who listen to the word, then follow the best of it; those are they whom Allah has guided, and those it is who are the men 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
