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 Meditate upon the name of 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 Surely these love the transitory and neglect a grievous day before them. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
