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 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 Remember the name of thy Lord at morn and evening. 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 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 whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
