We have indeed, sent down to you the Koran, a (clear) sending, 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and glorify your Lord morning and evening; 25 And prostrate for Him in a part of the night, and proclaim His purity into the 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, but, when We will, We shall indeed exchange their likes. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
