Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 Remember the name of thy Lord at morn and evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 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 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 maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
