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 (O Muhammad): Lo! I am commanded to worship Allah, making religion pure for Him (only). 11 And I am commanded that I shall be the first of those who submit. 12 Say: "I would, if I disobeyed my Lord, indeed have fear of the Penalty of a Mighty Day." 13 Say, "Allah [alone] do I worship, sincere to Him in my religion, 14 so serve what you will apart from Him.' Say: 'Surely the losers are they who lose themselves and their families on the Day of Resurrection; is not that the manifest loss? 15 They shall have coverings of Fire, above them and covering (of Fire) beneath them; with this Allah does frighten His slaves: "O My slaves, therefore fear Me!" 16 Those who shun the worship of idols and turn in repentance to Allah for them glad tidings. Therefore give good tidings to My worshipers, 17 Those who heed attentively and follow the best from it; it is these whom Allah has guided, and it is these who have intelligence. 18 Is, then, one against whom the decree of Punishment is justly due (equal to one who eschews Evil)? Wouldst thou, then, deliver one (who is) in the Fire? 19 But those who have feared their Lord - for them are chambers, above them chambers built high, beneath which rivers flow. [This is] the promise of Allah. Allah does not fail in [His] promise. 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
