It is We Who have sent down the Qur'an to thee by stages. 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 And celebrate the name of thy 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 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy 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 Verily this is an admonition; then whosoever will, may choose a way unto 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 whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
