Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 And remember the name of your Lord morning and evening. 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Verily those love the herein, and leave in front of them a heavy day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
