891/1164 (Sahih) From Abu Rifa’ah al-‘Adawi who said: I reached the Prophet, peace be upon him, while he was delivering a sermon, so I said: O Messenger of Allah! A stranger has come to ask about his religion, he does not know what his religion is. So he turned to me and left his sermon. A chair was brought to him, I thought its legs were made of iron — Humayd said: I think it was black wood, he thought it was iron — so he sat on it, and began teaching me from what Allah had taught him, then he completed his sermon; that was the last of it(1).
