We have indeed, sent down to you the Koran, a (clear) sending, 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 Mention the Name of your Lord, mornings and evenings. 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
