Musannaf Ibn Abi Shaybah 21156 — Two partners: those who said profit

Shurayh said: If a man makes a deal on credit and then takes another man into it as a partner, the liability is on the one who made the deal; if the other has paid no cash, nothing is due from him. If he has paid cash, the loss falls on the one who paid the cash, and the profit is divided according to the agreed share.
