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 worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
