The Legal Status of Condition of Capital's Guarantee in the Islamic Law

The contract of investment is a new issue which has no precedent on past. In this contract, Here is direct or indirect investment, the investor doesn’t invest his or her capital without sufficient guarantee from the other party so in the many indirect investment contract such condition may be inserted. This question, therefore, would propound that, the condition of capital’s guarantee is valid according to the Islamic law since a condition under Islamic law may be invalid and nullify the contract itself or be invalid but has no effect on the contract or valid. It seems that the condition is valid and the guarantor is binding to compensate the damage in the cases that are incurred.
