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]: "Behold, I am bidden to worship God, sincere in my faith in Him alone; 11 and I am bidden to be foremost among those who surrender themselves unto God." 12 Say: "Behold, I would dread, were I to rebel against my Sustainer, the suffering [which would befall me] on that awesome Day [of Judgment]." 13 Say: "God alone do I worship, sincere in my faith in Him alone 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 have an awning of fire above them and beneath them a dais (of fire). With this doth Allah appal His bondmen. O My bondmen, therefor fear Me! 16 But those who have avoided Taghut, lest they worship it, and turned back to Allah - for them are good tidings. So give good tidings to My servants 17 who listen to what is said and follow what is best in it. These are the ones God has guided; these are the people endowed with understanding. 18 So will the one upon whom the Word of punishment has proved true, ever be equal to those who are forgiven? So will you guide and save the one who deserves the fire? (Because the hearts of some disbelievers are sealed). 19 But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not 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
