Say: O my servants who believe! be careful of (your duty to) your Lord; for those who do good in this world is good, and Allah's earth is spacious; only the patient will be paid back their reward in full without measure. 10 Say, "I have been commanded to serve God, dedicating my worship entirely to Him. 11 And I have been commanded to be the first [among you] of the Muslims." 12 Say: I fear, if I disobey my Lord, the chastisement of a grievous day. 13 Say: 'God I serve, making my religion His sincerely; 14 So worship whatsoever ye will, besides him. Say thou: verily the losers are those who shall have lost themselves and their household on the Day of Judgment. Lo! that will be a loss manifest. 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 who listen to the Words and follow what is finest of it. These are they whom Allah has guided. They are those of understanding. 18 On the other hand, could one on whom [God's] sentence of suffering has been passed [be rescued by man]? Couldst thou, perchance, save one who is [already, as it were,] 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 Did you not see that it is Allah Who sent down water from the sky, and then with it made springs in the earth, and then with it produces crops of various colours, and then it dries up and you see it has become yellow, and He then fragments them into small pieces; indeed in this is a reminder for people of intellect. 21
