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: "Verily, I am commanded to serve Allah with sincere devotion; 11 I am ordered to be the first of those to be submissive (Muslims to Him)' 12 Say thou: verily I fear, if I disobeyed my Lord, torment of a Day mighty. 13 Say: "I worship God with devotion all-exclusive for Him. 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 to those who pay heed to what is said and follow the best of it. They are the ones whom Allah has guided to the Right Way; they are the ones endowed with understanding. 18 How can you rescue the one who is destined to suffer the torment? 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 Have you not seen that God sends down water from the sky, guides it to form springs in the earth, and then, with it, brings forth vegetation of various colours, which later withers, turns yellow before your eyes, and then He makes it crumble away? There is truly a reminder in this for those who possess understanding. 21
