Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 and bear in mind thy Sustainer's name at morn and evening 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 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
