We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 Remember the name of thy Lord at morn and evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put 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 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
