(O Prophet), indeed We have revealed the Qur'an to you in portions. 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 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
