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 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Surely these love the transitory and neglect a grievous day before them. 27 It is We Who created them, and We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement. 28 This chapter is a reminder. Let those who want, seek guidance from their Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
