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 your Lord every morning and afternoon [i.e. offering of the Morning (Fajr), Zuhr, and 'Asr prayers]. 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He admits whosoever He will to His benevolence. But for the evil-doers He has prepared a painful punishment. 31
