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 And celebrate the name of thy Lord morning and evening, 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
