Musannaf Ibn Abi Shaybah 23730 — A man who gives another man wealth

Yahya bin Abi Kathir spoke to al-Hakam bin Utaybah (about this), and he said: If he went back to his partner and informed him that his wealth had decreased, and the partner said: Go and work with what remains, then the profit is reckoned on five thousand, and they divide it. But if he did not say that to him, then the man's capital is ten thousand, and they divide whatever exceeds it.
