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 have been commanded to be the first of those that surrender.' 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 14 You may worship what you will apart from Him." Say: "Surely the greatest losers will be those who will lose their own selves and their people on the Day of Resurrection." Remember, this will be an all-too-evident loss. 15 There shall be sheets of fire above them and beneath them. This is the end against which Allah warns His servants. So dread My wrath, O you servants of Mine!” 16 seeing that for those who shun the powers of evil lest they [be tempted to] worship them, and turn unto God instead, there is the glad tiding [of happiness in the life to come]. Give, then, this glad tiding to [those of] My servants 17 Those who listen to the word, then follow the best of it; those are they whom Allah has guided, and those it is who are the men of understanding. 18 What! as for him then against whom the sentence of chastisement is due: What! can you save him who is in the fire? 19 As for those who fear their Lord, there await high mansions above which are built (more) high mansions, beneath which rivers flow, such is the promise of Allah; Allah will not fail 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
