Tell them (O Prophet): “O you servants of Mine who believe, have fear of your Lord. A good end awaits those who did good in this world. Allah's earth is spacious. Verily those who persevere shall be granted their reward beyond all reckoning.” 10 Say [O Muhammad]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say: 'Truly I fear, if I should rebel against my Lord, the chastisement of a dreadful day.' 13 Say, "It is God I serve, sincere in my faith in Him alone -- 14 So worship whatsoever ye will, besides him. Say thou: verily the losers are those who shall have lost themselves and their household on the Day of Judgment. Lo! that will be a loss manifest. 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 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 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 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 for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails in His promise. 20 Did you not see that it is Allah Who sent down water from the sky, and then with it made springs in the earth, and then with it produces crops of various colours, and then it dries up and you see it has become yellow, and He then fragments them into small pieces; indeed in this is a reminder for people of intellect. 21
