What is the meaning of the soul, and what is the difference between the soul and the self?

The questioner : I once, O Shaykh, had a question about the soul of Jibril. About what did he ask me?

The Shaykh : About its attribute. They want the Messenger to say something bad about it. Because they say that Jibril brings us evil. Excellent. (Peace and blessings be upon him). The souls of the children of Adam. About what? Even if, because he did not see anything but black. He did not see on Adam’s right or on his left anything but blackness, blackness meaning a darkness I do not know what it is, I do not know all of this. Therefore, even Adam, and Allah knows best, does not know about these souls. Yes.
The difference between the soul is that the self may be used for the soul. But it is broader than the soul. The soul is that by which life exists, and the self may be intended to mean that which manages the human being. Therefore, we divide the self into three categories: the tranquil self, the self that incites to evil, and the self that reprimands. And we do not divide the soul in this way.
But like the saying of the Messenger, “By Myself in His hand,” the intended meaning is the soul. Yes. And like his saying the intended meaning is the soul.
