We have indeed, sent down to you the Koran, a (clear) sending, 23 Therefore stay patient upon your Lord’s command, and do not listen to any of the sinners or ingrates among them. 24 And celebrate the name of thy Lord morning and evening, 25 And during the night - worship Him; and hallow Him the livelong night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto 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 makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
