Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And remember the name of 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 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
