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. onJumu'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 thetransmitters] said, 'I think that it was black wood like iron).'] He satdown on it and began to teach me what Allah had taught him. Then he finishedhis speech."
