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: "Verily, I am commanded to serve Allah with sincere devotion; 11 and I am bidden to be the first of those who surrender to Him.” 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: Allah I worship, making my religion pure for Him (only). 14 So worship what you like besides Him. Say (O Muhammad SAW): "The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest loss!" 15 They will have canopies of fire above them and below them, canopies. By that Allah threatens His servants. O My servants, then fear Me. 16 And those who avoid the devils lest they should worship them and turn unto Allah in penitence, for them are glad tidings. Wherefore give thou glad tidings unto My bondmen, 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 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 for those who truly feared their Lord, there will be tall mansions, built up storey upon storey, beneath which there will be rivers flowing. This is God's promise: God never fails 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
