If Someone Has Mudarabah Wealth, Is Zakah Due on It?

Hazrat Sha’bi says that there is no zakat on (money in) mudarabah. This is because one does not know what has been done with it.

Hazrat Abu Ja'far says that by Allah Almighty's command (wal-gharimeen) is meant those people who spend without causing corruption, and by ibn al-sabeel is meant those people who travel from one land to another (from one place to another).
