Say: O My bondmen who believe! Observe your duty to your Lord. For those who do good in this world there is good, and Allah's earth is spacious. Verily the steadfast will be paid their wages without stint. 10 Say [O Muhammad]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 I am ordered to be the first of those to be submissive (Muslims to Him)' 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say: "I worship God with devotion all-exclusive for Him. 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 coverings of fire above them and coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants! 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 Who listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding. 18 He against whom the word of chastisement is realized -- shalt thou deliver him out of the Fire? 19 Those who have fear of their Lord will have lofty mansions built upon mansions beneath which streams flow. It is the promise of God. God does not disregard His promise. 20 Do you not see that Allah sent down water from the sky, then made it flow on earth as springs and streams and rivers and then with it He brings forth vegetation of various hues; then this vegetation ripens and dries up, turning yellow, whereafter He reduces it to broken straw? Surely there is a lesson in this for those endowed with understanding. 21
