Verily We! it is We Who have revealed unto thee the Qur'an, 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 every morning and afternoon [i.e. offering of the Morning (Fajr), Zuhr, and 'Asr prayers]. 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Verily those love the herein, and leave in front of them a heavy day. 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
