Tell them (O Prophet): “O you servants of Mine who believe, have fear of your Lord. A good end awaits those who did good in this world. Allah's earth is spacious. Verily those who persevere shall be granted their reward beyond all reckoning.” 10 Say: 'I have been commanded to serve God making my religion His sincerely; 11 "And I am commanded to be the first of those who bow to Allah in Islam." 12 Say: I fear, if I disobey my Lord, the chastisement of a grievous day. 13 Say: "God alone do I worship, sincere in my faith in Him alone 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 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 those who stayed away from the worship of idols, and inclined towards Allah – for them are glad tidings; therefore give glad tidings to 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 On the other hand, could one on whom [God's] sentence of suffering has been passed [be rescued by man]? Couldst thou, perchance, save one who is [already, as it were,] in the fire? 19 But for those who fear displeasing their Lord there are lofty mansions built above mansions, with rivers rippling past below them: A promise of God; (and) God does not go back on His promise. 20 Do you not see that Allah sends down water from the cloud, then makes it go along in the earth in springs, then brings forth therewith herbage of various colors, then it withers so that you see it becoming yellow, then He makes it a thing crushed and broken into pieces? Most surely there is a reminder in this for the men of understanding. 21
