Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And glorify the name of your Lord morning and evening. 25 And worship Him (a portion) of the night. And glorify Him through the livelong 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 strengthened their joints; and whenever We wish, We can change their faces entirely. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He will admit to His Mercy whom He will and as for the Zalimun, (polytheists, wrong-doers, etc.) He has prepared a painful torment. 31
