We have indeed, sent down to you the Koran, a (clear) sending, 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And, remember the Name of your Lord at the dawn and in the evening; 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 It is We Who created them, and We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement. 28 Verily this is an admonition; then whosoever will, may choose a way unto 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
