Is it permissible to pay a sum of money to employees in a foreign country to complete a legitimate commercial transaction, knowing that failure to pay will lead to significant delays in procedures and incurring additional expenses, and there is no recourse for complaint?

It is impermissible for employees to take money from clients to complete their transactions, as this is a prohibited bribe, given that they already receive a salary for their work. As for the one who pays the money, if he cannot obtain his right or avert harm from himself except by paying a bribe, then it is permissible for him to do so, and the sin falls upon the employee. This is because the prohibited bribe is that by which a person obtains something to which he is not entitled, and there is no sin upon him if he is prevented from his right.
