We have indeed, sent down to you the Koran, a (clear) sending, 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
