Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 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 bear in mind thy Sustainer's name at morn and evening 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 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 whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
