Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 And, remember the Name of your Lord at the dawn and in the evening; 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 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 you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
