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], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 And I am commanded to be the first of those who submit." 12 Say: "If I disobey my Lord, I fear the punishment of an evil Day." 13 Say: 'God I serve, making my religion His sincerely; 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 will have sheets of fire above them and sheets of fire beneath them." That is how God puts fear into the hearts of His servants. Fear me, then, My servants. 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 to those who pay heed to what is said and follow the best of it. They are the ones whom Allah has guided to the Right Way; they are the ones endowed with 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 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 sends down rain from the sky and makes it flow as springs [and rivers] in the earth; then He produces thereby crops of varying colors; then they dry and you see them turned yellow; then He makes them [scattered] debris. Indeed in that is a reminder for those of understanding. 21
