(Muhammad), We have revealed the Quran to you in gradual steps. 23 Therefore be patient (O Muhammad SAW) and submit to the Command of your Lord (Allah, by doing your duty to Him and by conveying His Message to mankind), and obey neither a sinner nor a disbeliever among them. 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 was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
