Say: "O ye my servants who believe! Fear your Lord, good is (the reward) for those who do good in this world. Spacious is Allah's earth! those who patiently persevere will truly receive a reward without measure!" 10 Say: "I am commanded to worship God with obedience all-exclusive for Him; 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 14 “Therefore you can worship what you want besides Him!” Say, “The worst losers are those who will lose themselves and their household on the Day of Resurrection; pay heed! This is the plain 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 (On the other hand), good tidings await those who eschew serving false gods and penitently return to Allah. (O Prophet), give good tidings to My servants, 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 Is, then one against whom the Word of punishment justified (equal to the one who avoids evil). Will you (O Muhammad SAW) rescue him who is in the Fire? 19 But those who have feared their Lord - for them are chambers, above them chambers built high, beneath which rivers flow. [This is] the promise of Allah. Allah does not fail in [His] promise. 20 Do you not see that Allah sends down rain from the sky and makes it flow as springs [and rivers] in the earth; then He produces thereby crops of varying colors; then they dry and you see them turned yellow; then He makes them [scattered] debris. Indeed in that is a reminder for those of understanding. 21
