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 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 am afraid that for disobeying my Lord I shall suffer the torment of the great day". 13 Say, "It is God I serve, sincere in my faith in Him alone -- 14 "Serve ye what ye will besides him." Say: "Truly, those in loss are those who lose their own souls and their People on the Day of Judgment: Ah! that is indeed the (real and) evident Loss! 15 They have an awning of fire above them and beneath them a dais (of fire). With this doth Allah appal His bondmen. O My bondmen, therefor fear Me! 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 who listen [closely] to all that is said, and follow the best of it: [for] it is they whom God has graced with His guidance, and it is they who are [truly] endowed with insight! 18 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is in 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 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
