What is the ruling on mediating between a person who obtains building permits from the governorate through unknown means and others who wish to obtain these permits, and is it permissible to take money in exchange for this mediation?

If the license applicant is entitled to it but is unfairly denied, it is permissible for him to pay money to someone who can secure this right for him. This is not considered a forbidden bribe, because a forbidden bribe is that which is given to invalidate a right or uphold falsehood. However, if he is not entitled to the license, it is not permissible to intercede on his behalf or pay money for that purpose, as this falls under the prohibited bribe.
