Musannaf Ibn Abi Shayba 13:2756

Abu Bakr narrated to us, he said: Ibn 'Uyaynah narrated to us, from 'Amr, he said: A man said to Jabir ibn Zayd, "My father forbids me from his wealth; he says, 'I will not give you anything from it.'" He said, "Eat from your father's wealth in a reasonable manner."
