We have revealed the Qur'an to you gradually; 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 Mention the Name of your Lord, mornings and evenings. 25 Prostrate before Him and glorify Him extensively during the night. 26 Behold, they [who are unmindful of God] love this fleeting life, and leave behind them [all thought of] a grief-laden 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
