“I once asked one of the two Imam, (abu Ja’far or abu ’Abd Allah), ‘Alayhim al-Salam, about the case of a man who gave a certain amount of assets to another man for Mudarabah (profit sharing) and prohibited him from taking it out with him, but he went out. He (the Imam) said, ‘He is held responsible for the assets and the profit is for both.’”
