Say: 'My servants who believe, fear your Lord. For those who do good in this world good, and God's earth is wide. Surely the patient will be paid their wages in full without reckoning.' 10 Say: "I am commanded to worship God with obedience all-exclusive for Him; 11 "And I am commanded (this) in order that I may be the first of those who submit themselves to Allah (in Islam) as Muslims." 12 Say: I fear, if I disobey my Lord, the chastisement of a grievous day. 13 Say, "I worship God alone and devote myself to His religion. 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 Above them they shall have layers of fire and beneath them layers. By this Allah puts fear into His worshipers' 'O My worshipers, fear Me' 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 (Muhammad), give the glad news to those of Our servants who listen to the words and only follow the best ones. Tell them that they are those whom God has guided. They are the people of understanding. 18 Can he against whom the sentence of punishment has been justified (be rescued)? Can you save him who is in the Fire? 19 But those who fear their Lord -- for them await lofty chambers, above which are built lofty chambers, underneath which rivers flow -- God's promise; God fails not the tryst. 20 Do you not see that Allah sent down water from the sky, then made it flow on earth as springs and streams and rivers and then with it He brings forth vegetation of various hues; then this vegetation ripens and dries up, turning yellow, whereafter He reduces it to broken straw? Surely there is a lesson in this for those endowed with understanding. 21
