Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and bear in mind thy Sustainer's name at morn and evening 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
