Truly, it is We who have revealed to you the Quran, a gradual 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 worship Him (a portion) of the night. And glorify Him through the livelong 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 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
