Lo! We, even We, have revealed unto thee the Qur'an, a revelation; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And glorify the name of your Lord morning and evening. 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put 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 he who will, takes unto 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
