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 anyone among them who is sinful or ungrateful; 24 Remember the name of thy Lord at morn and evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous 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 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
