Lo! We, even We, have revealed unto thee the Qur'an, a revelation; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember the name of your Lord morning and evening. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
