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 this, in order I may be the first of those who submit. 12 Say: "If I disobey my Lord, I fear the punishment of an evil Day." 13 Say: 'I worship Allah and make my religion sincerely His. 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 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 There are happy tidings for those who keep away from the worship of false gods and turn to God in repentance. Give glad tidings to My creatures. 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 fear their Lord -- for them await lofty chambers, above which are built lofty chambers, underneath which rivers flow -- God's promise; God fails not the tryst. 20 Hast thou not seen how Allah hath sent down water from the sky and hath caused it to penetrate the earth as watersprings, and afterward thereby produceth crops of divers hues; and afterward they wither and thou seest them turn yellow; then He maketh them chaff. Lo! herein verily is a reminder for men of understanding. 21
