It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: I saw the Messenger of Allah (peace and blessings be upon him and his family) talking to a man with his hand placed on the neck of a horse. I said, "I saw you talking to someone with your hand placed on the neck of Dihya Kalbi's horse." The Prophet (peace and blessings be upon him and his family) said, "Did you see that?" I replied, "Yes." The Prophet (peace and blessings be upon him and his family) said, "That was Jibreel (Gabriel), and he was conveying greetings of peace to you." I replied, "And peace, mercy, and blessings of Allah be upon him. May Allah reward this companion and guest with goodness; he is the best companion and the best guest." Imam Ahmad's teacher, Imam Sufyan bin Uyaynah, explained that "al-dakhil" means guest.
