Truly, it is We who have revealed to you the Quran, a gradual revelation. 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 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Surely these love the transitory and neglect a grievous day before them. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
