A man invited the Prophet (may Allah's peace and blessings be upon him) with four others to a meal. A man followed them, and thus they became six altogether. When the Prophet (may Allah's peace and blessings be upon him) arrived at the house of the host, he asked permission for the sixth man, saying: "This man followed us. If you wish, allow him to come in, and if you wish, he will go back." So the host allowed the man to join them in honor of the Messenger of Allah (may Allah's peace and blessings be upon him).
