Al-Adab Al-Mufrad: Behaviour with people – Hadith No. 1167 — I came to the Messenger of Allah, may Allah bless him and grant him peace… (Hadith No. 1167)

Abu Rifa'a al-'Adawi said, "I came to the Messenger of Allah,
may Allah bless him and grant him peace, while he was speaking [i.e. on
Jumu'a]. I said, 'Messenger, a stranger man has come to ask about his deen.
He does not know what his deen is.' He turned to me and stopped speaking.
He was brought a chair which I think had iron legs. (Hamid [one of the
transmitters] said, 'I think that it was black wood like iron).'] He sat
down on it and began to teach me what Allah had taught him. Then he finished
his speech."
