We have indeed, sent down to you the Koran, a (clear) sending, 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 And remember the name of 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 Surely men love what hastes away and forget the grievous day (ahead). 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 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
