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 Mention the Name of your Lord, mornings and evenings. 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
