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 Mention the Name of your Lord, mornings and evenings. 25 And bow in homage part of the night, and glorify Him far into the night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
