We have revealed the Qur'an to you gradually; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember the name of your Lord morning and evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Surely these love the transitory and neglect a grievous day before them. 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 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
