Say: O my servants who believe! be careful of (your duty to) your Lord; for those who do good in this world is good, and Allah's earth is spacious; only the patient will be paid back their reward in full without measure. 10 Say, "I have been commanded to serve God, dedicating my worship entirely to Him. 11 and I am bidden to be the first of those who surrender to Him.” 12 Say: 'Indeed, if I rebel against my Lord I fear the punishment of a dreadful Day' 13 Say, "It is God I serve, sincere in my faith in Him alone -- 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 Above and below them their will be shadows of fire. This is how God frightens His servants. My servants have fear of 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 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 So will the one upon whom the Word of punishment has proved true, ever be equal to those who are forgiven? So will you guide and save the one who deserves the fire? (Because the hearts of some disbelievers are sealed). 19 But those who fear their Lord, for them are lofty chambers with lofty chambers above them, built whereunder rivers flow: the promise of Allah, and Allah faileth not the appointment. 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
