An Ansari companion (may Allah be pleased with him) says that once I left my house with the intention of presenting myself before the Prophet Muhammad (peace and blessings be upon him). When I arrived there, I saw that the Prophet Muhammad (peace and blessings be upon him) was standing, and with him was another man whose face was towards the Prophet (peace and blessings be upon him). I thought that perhaps the two were discussing something important. By Allah! The Prophet (peace and blessings be upon him) stood for so long that I began to feel pity for him. When that man left, I said, "O Messenger of Allah! This man kept you standing for so long that I began to feel pity for you." The Prophet (peace and blessings be upon him) said, "Did you see him?" I replied, "Yes." The Prophet (peace and blessings be upon him) said, "Do you know who he was?" I replied, "No." The Prophet (peace and blessings be upon him) said, "He was Jibreel (Gabriel, peace be upon him), who kept advising me continuously about the neighbor until I thought he would make him an heir in inheritance." Then he said, "If you had greeted him, he would surely have replied to you."
