Lo! We, even We, have revealed unto thee the Qur'an, a revelation; 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And mention the name of your Lord [in prayer] morning and evening 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 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 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
