Say: "[Thus speaks God:] 'O you servants of Mine who have attained to faith! Be conscious of your Sustainer! Ultimate good awaits those who persevere in doing good in this world. And [remember:] wide is God's earth, [and,] verily, they who are patient in adversity will be given their reward in full, beyond all reckoning!'" 10 Say, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 And I am commanded that I shall be the first of those who submit. 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 14 (As for yourselves) worship what you will, other than Him' Say: 'The losers are surely those who lose themselves and their families on the Day of Resurrection. Is that not a clear loss' 15 Above and below them their will be shadows of fire. This is how God frightens His servants. My servants have fear of Me. 16 Those who eschew the serving of idols and turn penitent to God, for them is good tidings! So give thou good tidings to My servants 17 Who listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people 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 keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not 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
