Musannaf Ibn Abi Shaybah 32890 — A man who makes a bequest and says

Abu Bakr bin Amr bin Hazm said: A young boy from Ghassan lived in Madinah, whose heirs lived in Syria, and he had a paternal aunt in Madinah. When the time of his death drew near, his aunt came to Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), mentioned the boy's condition, and asked: Can that boy make a will? He said: Has he reached puberty? He said: I said: No. He said: Then he can make a will. He said: The boy then made a bequest of a palm grove to his aunt. The narrator said: I sold that palm grove for that woman for thirty thousand dirhams.
