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 thy Lord at dawn and in the evening 25 And during the night - worship Him; and hallow Him the livelong night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
