Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember the name of your Lord morning 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 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 Verily! This (Verses of the Quran) is an admonition, so whosoever wills, let him take a Path to his Lord (Allah). 29 And you do not will except that Allah wills. Indeed, Allah is ever 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
