VERILY, [O believer,] it is We who have bestowed from on high this Qur'an upon thee, step by step - truly a bestowal from on high! 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 Remember the name of thy Lord at morn and evening. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Surely these love the transitory and neglect a grievous day before them. 27 We created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
