Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And remember the Name of thy Lord at dawn and in the evening 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
