(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 and glorify your Lord morning and evening; 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
