Musnad Ahmad 287:4

Rawh narrated to us, he said: Umar ibn Sa’id ibn Abi Husayn narrated to us, he said: Abdullah ibn Abi Mulaykah narrated to me, from Uqbah ibn 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 salutation, he stood up quickly and entered upon some of his wives. Then he came out and saw the astonishment on the faces of the people due to his haste. 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." Abu Ahmad al-Zubayri narrated to us, he said: Umar ibn Sa’id narrated to us, from Ibn Abi Mulaykah, from Uqbah ibn al-Harith, who said: The Messenger of Allah, peace and blessings of Allah be upon him, departed when he had prayed the Asr prayer, and he mentioned its meaning.
