Musnad Ahmad 482:145

Ishaq ibn Isa and Musa ibn Dawud narrated to us, they said: Ibn Lahi'ah narrated to us, from Yazid ibn Abi Habib, from Abu al-Khayr, from Uqbah ibn Amir: That a young man came to the Prophet, may Allah bless him and grant him peace—and Musa said in his narration: A man asked the Messenger of Allah, may Allah bless him and grant him peace—and he said: "O Messenger of Allah, my mother died and left behind jewelry; shall I give charity on her behalf with it?" He said: "Did your mother command you to do that?" He said: "No." He said: "Then keep your mother's jewelry for yourself." Abu Abd al-Rahman, meaning al-Muqri, narrated it to us.
