Musnad Ahmad 778:4

Rawh narrated to us, Umar bin Sa'id bin Abi Husayn narrated to us, he said: Abdullah bin Abi Mulaykah informed me, from Uqbah bin al-Harith, who said: I prayed the Asr prayer with the Messenger of Allah, peace and blessings of Allah be upon him. When he finished the prayer with the taslim, he stood up quickly and entered upon some of his wives, then he came out. He saw the astonishment on the faces of the people due to his haste, so he said: "I remembered, while I was in the prayer, some gold we had, and I disliked that it should remain with us until evening or overnight, so I ordered it to be distributed."
