Say, "[God says] O My servants who have believed, fear your Lord. For those who do good in this world will have a good reward -- and God's earth is spacious. Truly, those who persevere patiently will be requited without measure." 10 Say [O Muhammad]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 and I have been commanded to be the first of those that surrender.' 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say, "I worship God alone and devote myself to His religion. 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 those who avoid the devils lest they should worship them and turn unto Allah in penitence, for them are glad tidings. Wherefore give thou glad tidings unto My bondmen, 17 who listen to the Words and follow what is finest of it. These are they whom Allah has guided. They are those of understanding. 18 (O Prophet), can you save him (from chastisement) against whom the sentence of chastisement has become due; him who has, (as it were), already fallen into the Fire?” 19 But for those who fear displeasing their Lord there are lofty mansions built above mansions, with rivers rippling past below them: A promise of God; (and) God does not go back on 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
