It is We Who have sent down the Qur'an to thee by stages. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 And mention the name of your Lord [in prayer] morning and evening 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
