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 have been commanded to be the first [among you] of the Muslims." 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: Allah (it is Whom) I serve, being sincere to Him in my obedience: 14 so serve what you will apart from Him.' Say: 'Surely the losers are they who lose themselves and their families on the Day of Resurrection; is not that the manifest 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 Those who eschew Evil,- and fall not into its worship,- and turn to Allah (in repentance),- for them is Good News: so announce the Good News to My Servants,- 17 to those who pay heed to what is said and follow the best of it. They are the ones whom Allah has guided to the Right Way; they are the ones endowed with understanding. 18 Is he then on whom is justified the decree of torment - wilt thou rescue him who is in the Fire? 19 But for those who fear displeasing their Lord there are lofty mansions built above mansions, with rivers rippling past below them: A promise of God; (and) God does not go back on 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
