Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 Remember the name of thy Lord at morn and evening. 25 And during the night - worship Him; and hallow Him the livelong 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 strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
