Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 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 the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 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 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
