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 am bidden to be foremost among those who surrender themselves unto God." 12 Say: "I would, if I disobeyed my Lord, indeed have fear of the Penalty of a Mighty Day." 13 Say, "It is God I serve, sincere in my faith in Him alone -- 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 They shall have Layers of Fire above them, and Layers (of Fire) below them: with this doth Allah warn off his servants: "O My Servants! then fear ye Me!" 16 And those who stayed away from the worship of idols, and inclined towards Allah – for them are glad tidings; therefore give glad tidings to 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 He against whom the word of chastisement is realized -- shalt thou deliver him out of the Fire? 19 But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not His promise. 20 Have you not seen that God has sent down water from the sky and made it flow as springs out of the earth? He makes crops of different colors grow with this water and flourish, which then turn yellow and wither away. In this there is a reminder for the people of understanding. 21
