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 and remember the name of your Lord, morning and evening; 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
