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): Lo! I am commanded to worship Allah, making religion pure for Him (only). 11 And I am commanded to be the first of those who submit." 12 Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day." 13 Say: 'I worship Allah and make my religion sincerely His. 14 Serve then what you like besides Him. Say: The losers surely are those who shall have lost themselves and their families on the day of resurrection; now surely that is the clear 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 seeing that for those who shun the powers of evil lest they [be tempted to] worship them, and turn unto God instead, there is the glad tiding [of happiness in the life to come]. Give, then, this glad tiding to [those of] My servants 17 who listen to what is said and follow what is best in it. These are the ones God has guided; these are the people 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 those who fear their Lord shall have lofty mansions built over one another beneath which rivers flow. This is Allah's promise and never does Allah fail to fulfil His promise. 20 Did you not see that it is Allah Who sent down water from the sky, and then with it made springs in the earth, and then with it produces crops of various colours, and then it dries up and you see it has become yellow, and He then fragments them into small pieces; indeed in this is a reminder for people of intellect. 21
