We have indeed, sent down to you the Koran, a (clear) sending, 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 and glorify your Lord morning and evening; 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 This is indeed a Reminder, so that he who will, takes a 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 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
