We have revealed the Qur'an to you gradually; 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 and glorify your Lord morning 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 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 And you do not will except that Allah wills. Indeed, Allah is ever 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
