Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And celebrate the name of thy Lord morning and evening, 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Indeed, these love the hasty life, and are heedless and leave behind 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 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
