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): Lo! I am commanded to worship Allah, making religion pure for Him (only). 11 And I am commanded this, in order I may be the first of those who submit. 12 Say: Lo! if I should disobey my Lord, I fear the doom of a tremendous Day. 13 Say: "I worship God with devotion all-exclusive for Him. 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 There shall be sheets of fire above them and beneath them. This is the end against which Allah warns His servants. So dread My wrath, O you servants of Mine!” 16 (On the other hand), good tidings await those who eschew serving false gods and penitently return to Allah. (O Prophet), give good tidings to My servants, 17 Those who listen to the Word, and follow the best (meaning) in it: those are the ones whom Allah has guided, and those are the ones endued with understanding. 18 How can you rescue the one who is destined to suffer the torment? 19 But those who fear their Lord shall have lofty mansions built over one another beneath which rivers flow. This is Allah's promise and never does Allah fail to fulfil 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
