We have revealed the Qur'an to you gradually; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And mention the name of your Lord [in prayer] morning and evening 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Surely these love the transitory and neglect a grievous day before them. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Indeed, this is a reminder, so he who wills may take to his Lord 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 admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
