Is it permissible to pay an amount to a brokerage firm to obtain a loan or real estate through an Islamic bank, knowing that the amount is determined as a percentage of the value of the loan or real estate?

It is permissible to act as an intermediary in obtaining a qard hasan (interest-free loan) or in purchasing a property that is religiously permissible. However, it is not permissible to do so for an interest-bearing loan or for purchasing something forbidden.

Types of Intermediation: 1. Brokerage (Dallalah/Samsarah): Permissible for a fixed fee or a percentage of the loan or price. 2. Intermediation through Prestige and Intercession (Al-Jah wal-Shafa'ah): The preponderant opinion is that it is permissible to take a commission for it. 3. Guaranty (Daman): It is not permissible to take a commission for it, as it is a contract of donation (tabarru'), and scholars have reached a consensus on its prohibition.
