(17:80) And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." (17:81) And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." (17:82) And We send down of the Qur`an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss. (17:83) And when We bestow favor upon the disbeliever, he turns away and distances himself; and when evil touches him, he is ever despairing. (17:84) Say, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." (17:85) And they ask you, [O Muhammad], about the soul. Say, "The soul is of the affair of my Lord. And mankind have not been given of knowledge except a little." (17:86) And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us.
