“I saw the Prophet (Allah bless him and give him peace) in my sleep in the time of Ibn 'Abbas, so I said to Ibn 'Abbas:‘I saw Allah’s Messenger (Allah bless him and give him peace) in my sleep!’Ibn 'Abbas said: “Allah’s Messenger (Allah bless him and give him peace) used to say: ‘Satan cannot imitate me, so if someone sees me in his sleep, he has indeed seen me!’ Can you describe this man whom you saw in your sleep?” “Yes,” he said. “I shall describe for you an average man: his body and his flesh were brown-to-white; he was black eyed, endowed with a pleasant smile and handsome facial features; his beard went from here to here, and it came down over the top of his chest.”'Awf said: "I do not know what could be added to this description,” and Ibn 'Abbas said: "If you had seen him in the state of wakefulness, you could not have described him more accurately than this.”
