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): Lo! I am commanded to worship Allah, making religion pure for Him (only). 11 And I have been commanded to be the first [among you] of the Muslims." 12 Say, "I fear, if I disobey my Lord, the punishment of a Terrible Day." 13 Say: Allah (it is Whom) I serve, being sincere to Him in my obedience: 14 (As for yourselves) worship what you will, other than Him' Say: 'The losers are surely those who lose themselves and their families on the Day of Resurrection. Is that not a clear loss' 15 Above and below them their will be shadows of fire. This is how God frightens His servants. My servants have fear of Me. 16 And (as for) those who keep off from the worship of the idols and turn to Allah, they shall have good news, therefore give good news to My servants, 17 Those who listen to the Word and then follow the best it contains, are the ones who have been guided by God, and are men of wisdom. 18 Can you save from the Fire he whom against the word of punishment has been realized? 19 But those who fear their Lord, for them are lofty chambers with lofty chambers above them, built whereunder rivers flow: the promise of Allah, and Allah faileth not the appointment. 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
