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 during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 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 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 (The virtuous mentioned in this chapter) want only what God wants. God is All-knowing and All-wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
