Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an 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 prostrate yourself before Him at night, and extol His Glory during the long watches 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 this is an admonition; then whosoever will, may choose a way unto his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
