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 Tell them, (O Prophet): “I am bidden to serve Allah, consecrating my devotion to Him, 11 and I have been commanded to be the first of those that surrender.' 12 Say: “If I disobey my Lord, I fear the chastisement of an Awesome Day.” 13 Say: “Allah alone shall I serve, consecrating my devotion to Him. 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 For them! above them shall be coverings of Fire and beneath them coverings. Therewith Allah affrighteth His bondmen. O My bondmen! wherefore 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 listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding. 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 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 Have you not seen how Allah sends down water from the sky and threaded it as springs in the earth? Then, He brings forth plants of various colors, after which they wither, and you see them turning yellow, and then He makes them into broken stubble. Surely, in this there is a reminder for those of understanding. 21
