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 bear in mind thy Sustainer's name at morn and evening 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But you will not desire except as God wills. Verily He 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
