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 [among you] of the Muslims." 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 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 will have sheets of fire above them and sheets of fire beneath them." That is how God puts fear into the hearts of His servants. Fear me, then, My servants. 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 Those who heed attentively and follow the best from it; it is these whom Allah has guided, and it is these who have intelligence. 18 How can you rescue the one who is destined to suffer the torment? 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 Hast thou not seen how Allah hath sent down water from the sky and hath caused it to penetrate the earth as watersprings, and afterward thereby produceth crops of divers hues; and afterward they wither and thou seest them turn yellow; then He maketh them chaff. Lo! herein verily is a reminder for men of understanding. 21
