Is it permissible to take money from an Islamic bank if it profits, with a guarantee of capital recovery in case of loss through a reconciliation agreement?

A Mudarabah contract that includes a condition guaranteeing the capital is impermissible. The fact that the bank voluntarily guarantees the capital in case of loss, under what it calls a "reconciliation contract," does not make the contract permissible as long as this condition is stipulated within it.
