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 Meditate upon the name of your Lord morning and evening; 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
