Surely We have sent down the Koran on thee, a sending down; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 Meditate upon the name of your Lord morning and evening; 25 And bow in homage part of the night, and glorify Him far into the night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 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
