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 at the dawn and in the evening; 25 Prostrate before Him and glorify Him extensively during the night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
