Say to My believing servants, "Have fear of your Lord. Those who act righteously in this life will receive good reward. The land of God is vast. God will recompense the deeds of those who have exercised patience, without keeping an account". 10 Say, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 and I have been commanded to be the first of those that surrender.' 12 Say: "Behold, I would dread, were I to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]." 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 14 So worship what you will besides Him." Say, "Indeed, the losers are the ones who will lose themselves and their families on the Day of Resurrection. Unquestionably, that is 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 And (as for) those who keep off from the worship of the idols and turn to Allah, they shall have good news, therefore give good news 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 What! as for him then against whom the sentence of chastisement is due: What! can you save him who is in the fire? 19 But for those who fear their Lord, are the high chambers with more high chambers built above them – rivers flowing beneath them; a promise of Allah; Allah does not renege on His promise. 20 Do you not see that Allah sent down water from the sky, then made it flow on earth as springs and streams and rivers and then with it He brings forth vegetation of various hues; then this vegetation ripens and dries up, turning yellow, whereafter He reduces it to broken straw? Surely there is a lesson in this for those endowed with understanding. 21
