(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 glorify your Lord morning and evening; 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
