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 And remember thou the name of thy Lord in the morning and in the evening. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 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 whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
