Musnad Abi Ya'la 5669 — I came to Madinah, and Sayyiduna Abdullah bin

Abu Burdah (may Allah have mercy on him) narrates: I came to Madinah, and Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) came to me and asked: "Do you know why I have come to you?" He says: I said: "No." He said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Whoever would like to maintain ties with his father in his grave (that is, after his death) and treat him kindly, let him maintain ties with his father's brothers and friends after him." And the fact is that between my father, Sayyiduna Umar (may Allah be pleased with him), and your father there was deep brotherhood and heartfelt affection, so I wished to maintain that old bond and keep it up."
