What were the words of wisdom that the Prophet Muhammad (saw) imparted to Abu Rifa'a when he asked about knowledge of the religion?
 Abu Rifa'a reported:                      I came to the Holy Prophet (may peace be upon him) when he was delivering the sermon, and I said: Messenger of Allah, here is a stranger and he wants to learn about this religion and he does not know what this religion is. The Messenger of Allah (may peace be upon him) looked at me and left his sermon till he came to me, and he was given a chair and I thought that Its legs were made of iron. The Messenger of Allah (may peace be upon him) sat In it and he began to teach me what Allah had taught him. He then came (to the pulpit) for his sermon and completed it to the end.
