We have revealed the Qur'an to you gradually; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and glorify your Lord morning and evening; 25 Prostrate before Him and glorify Him extensively during the night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
