Say: "O ye my servants who believe! Fear your Lord, good is (the reward) for those who do good in this world. Spacious is Allah's earth! those who patiently persevere will truly receive a reward without measure!" 10 Say, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 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, "Allah [alone] do I worship, sincere to Him in my religion, 14 and [it is up to you, O sinners, to] worship whatever you please instead of Him!" Say: "Behold, the [true] losers will be they who shall have lost their own selves and their kith and kin on Resurrection Day: for is not this, this, the [most] obvious loss? 15 They shall have coverings of fire above them and coverings beneath them; with that Allah makes His servants to fear, so be careful of (your duty to) Me, O My servants! 16 seeing that for those who shun the powers of evil lest they [be tempted to] worship them, and turn unto God instead, there is the glad tiding [of happiness in the life to come]. Give, then, this glad tiding to [those of] My servants 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of understanding. 18 Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is in the Fire? 19 Those who have fear of their Lord will have lofty mansions built upon mansions beneath which streams flow. It is the promise of God. God does not disregard 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
