(Muhammad), We have revealed the Quran to you in gradual steps. 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 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
