When the revelation descended on the Prophet of Allāh - peace and blessing of Allāh be upon him and his descendants - I heard the moan of Satan. I said, “O Prophet of Allāh, what is this moan?” and he replied, “This is Satan who has lost all hope of being worshipped. O ‘Alī, you see all that I see and you hear all that I hear, except that you are not a Prophet, but you are a vicegerent and you are surely on (the path of) virtue.”
