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 am commanded this, in order I may be the first of those who submit. 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 Serve then what you like besides Him. Say: The losers surely are those who shall have lost themselves and their families on the day of resurrection; now surely that is the clear loss. 15 They shall have Layers of Fire above them, and Layers (of Fire) below them: with this doth Allah warn off his servants: "O My Servants! then fear ye Me!" 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of understanding. 18 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is 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 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
