It is narrated from Hazrat Aisha (may Allah be pleased with her) that once I saw the Prophet (peace and blessings be upon him) with his hand on the head of a horse, talking to a man. Later, I said, "I saw you with your hand on the head of Dihya Kalbi's horse, talking to a man." The Prophet (peace and blessings be upon him) asked, "Did you see him?" I replied, "Yes!" The Prophet (peace and blessings be upon him) said, "That was Jibreel (Gabriel), and he was conveying greetings of peace to you." I replied, "And peace be upon him, and the mercy of Allah and His blessings. May Allah reward him with goodness, both the host and the guest, for the host is excellent and the guest is excellent."
