Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 and bear in mind thy Sustainer's name at morn and evening 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous 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 This is indeed a Reminder, so that he who will, takes a 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 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
