We have indeed, sent down to you the Koran, a (clear) sending, 23 Therefore stay patient upon your Lord’s command, and do not listen to any of the sinners or ingrates among them. 24 and glorify your Lord morning and evening; 25 And during night, prostrate yourself to Him (i.e. the offering of Maghrib and 'Isha' prayers), and glorify Him a long night through (i.e. Tahajjud prayer). 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
