Tell them: "O my creatures who have come to belief, have fear of displeasing your Lord. There is good for those who do good in this world, and productive is God's earth. Only those who persevere will get their reward measureless." 10 Say, [O Muhammad], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 “And I am commanded that I be the first to submit.” 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 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 Clouds of fire will they have above them, and [similar] clouds beneath them…" In this way does God imbue His servants with fear. O you servants of Mine! Be, then, conscious of Me 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 Who listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding. 18 Is he then on whom is justified the decree of torment - wilt thou rescue him 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 Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. Truly, in this, is a Message of remembrance to men of understanding. 21
