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 Tell them, (O Prophet): “I am bidden to serve Allah, consecrating my devotion to Him, 11 And I am commanded to be the first of those who submit." 12 Say: "I would, if I disobeyed my Lord, indeed have fear of the Penalty of a Mighty Day." 13 Say: "I worship God with devotion all-exclusive for Him. 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 Above them are mountains of fire and beneath them are mountains of fire; Allah scares His bondmen with this; “O My bondmen! Fear Me!” 16 Those who have avoided worshipping idols and have turned in repentance to God will receive the glad news. 17 Who hear advice and follow the best thereof. Such are those whom Allah guideth, and such are men of 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 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 Beholdest thou not that Allah sendeth down water from the heaven, and causeth it to enter springs in the earth, and thereafter produceth thereby corn various coloured. Thereafter it wirhereth, and thou beholdest it turn yellow; then He maketh it chaff. Verily herein is an admonition for men of understanding. 21
