Al-Adab Al-Mufrad #126

Jabir said, "A man came to the Prophet, may Allah bless him and grant him peace, to complain to him about the enmity of his neighbour. While he was sitting between the Corner and the Maqam, the Prophet, may Allah bless him and grant him peace, approached with a man who was wearing a white garment. They went to the Maqam where they were praying for the dead. He went up to the Prophet, may Allah bless him and grant him peace, and said, 'May my mother and my father be your ransom, Messenger of Allah! Who is this man I see with you wearing the white garment?' 'You saw him?' he asked. 'Yes,' the man replied. He said, 'Then you have seen much good. That was Jibril, may Allah bless him and grant him peace, the Messenger of my Lord. He kept on recommending that I treat my neighbours well until I thought that he would order me to make them my heirs.'"
