Abu Rifa'a al-'Adawi said, "I came to the Messenger of Allah (ﷺ) 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."
