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 thy Lord at dawn and in the evening 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He admits whosoever He will to His benevolence. But for the evil-doers He has prepared a painful punishment. 31
