VERILY, [O believer,] it is We who have bestowed from on high this Qur'an upon thee, step by step - truly a bestowal from on high! 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 and glorify your Lord morning and evening; 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 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 will admit to His Mercy whom He will and as for the Zalimun, (polytheists, wrong-doers, etc.) He has prepared a painful torment. 31
