Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: When Sayyiduna Abbas bin Abdul Muttalib (may Allah be pleased with him) would give his wealth to someone as mudarabah (profit-sharing partnership), he would stipulate the condition that the person should not travel by sea with that wealth, should not camp with it in any (valley (i.e., barren) place, should not purchase any living creature with it, and if he did so, he would be liable (to pay compensation) for it. Then he mentioned this condition before the Noble Prophet (peace and blessings be upon him), and he approved it.
