It is We Who have sent down the Qur'an to thee by stages. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And, remember the Name of your Lord at the dawn and in the evening; 25 Prostrate before Him and glorify Him extensively during the night. 26 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Indeed, this is a reminder, so he who wills may take 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
