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], "Indeed, I have been commanded to worship Allah, [being] sincere to Him in religion. 11 And I am commanded to be the first of those who submit." 12 Say, "I am afraid that for disobeying my Lord I shall suffer the torment of the great day". 13 Say: "It is Allah I serve, with my sincere (and exclusive) devotion: 14 So worship whatsoever ye will, besides him. Say thou: verily the losers are those who shall have lost themselves and their household on the Day of Judgment. Lo! that will be a loss manifest. 15 There shall be sheets of fire above them and beneath them. This is the end against which Allah warns His servants. So dread My wrath, O you servants of Mine!” 16 Those who eschew Evil,- and fall not into its worship,- and turn to Allah (in repentance),- for them is Good News: so announce the Good News to My Servants,- 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 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 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 Have you not seen that God sends down water from the sky, guides it to form springs in the earth, and then, with it, brings forth vegetation of various colours, which later withers, turns yellow before your eyes, and then He makes it crumble away? There is truly a reminder in this for those who possess understanding. 21
