Musnad Ahmad 1153:213

Yahya narrated to us, from Muhammad ibn ‘Amr, who said: Abu Salamah narrated to me, saying: ‘Aishah said: The Messenger of Allah (peace and blessings of Allah be upon him) said during his illness in which he died: "O ‘Aishah, what has been done with the gold?" So she brought an amount between five and seven, or eight, or nine. He began to turn them over in his hand and said: "What would Muhammad’s opinion of Allah (Mighty and Majestic is He) be if he were to meet Him while this is in his possession? Spend it."
