VERILY, [O believer,] it is We who have bestowed from on high this Qur'an upon thee, step by step - truly a bestowal from on high! 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 part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-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
