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 thou the name of thy Lord in the morning and in the evening. 25 and in the night prostrate to Him; and exalt Him for a long 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 Surely this is a reminder, so whoever pleases takes 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 whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
