Tell them (O Prophet): “O you servants of Mine who believe, have fear of your Lord. A good end awaits those who did good in this world. Allah's earth is spacious. Verily those who persevere shall be granted their reward beyond all reckoning.” 10 Say thou: verily I am commanded to worship Allah, making for Him religion exclusive. 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: Allah (it is Whom) I serve, being sincere to Him in my obedience: 14 "Serve ye what ye will besides him." Say: "Truly, those in loss are those who lose their own souls and their People on the Day of Judgment: Ah! that is indeed the (real and) evident Loss! 15 They will have canopies of fire above them and below them, canopies. By that Allah threatens His servants. O My servants, then fear Me. 16 And those who put away false gods lest they should worship them and turn to Allah in repentance, for them there are glad tidings. Therefor give good tidings (O Muhammad) to My bondmen 17 who give ear to the Word and follow the fairest of it. Those are they whom God has guided; those -- they are men possessed of minds. 18 He against whom the word of chastisement is realized -- shalt thou deliver him out of 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 See you not, that Allah sends down water (rain) from the sky, and causes it to penetrate the earth, (and then makes it to spring up) as water-springs and afterward thereby produces crops of different colours, and afterward they wither and you see them turn yellow, then He makes them dry and broken pieces. Verily, in this, is a Reminder for men of understanding. 21
