(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 Meditate upon 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 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Verily! This (Verses of the Quran) is an admonition, so whosoever wills, let him take a Path to his Lord (Allah). 29 But you will not unless God wills; surely God is ever All-knowing, All-wise. 30 He admits unto His grace everyone who wills [to be admitted]; but as for the evildoers - for them has He readied grievous suffering [in the life to come]. 31
