It is We Who have sent down the Qur'an to thee by stages. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 And glorify the name of your Lord morning and evening. 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
