What is the ruling on completing a deal in which it was discovered that part of the price paid to the broker was a bribe to a marketing official, without the knowledge of the owning company?

If you know that the matter involves deception, fraud, and unlawful appropriation of the company owner's money, then it is not permissible for you to assist in that by recording a fictitious invoice, due to the Almighty's saying: "And do not cooperate in sin and aggression," and His saying: "And do not consume your properties among yourselves through falsehood." It is obligatory to advise those in charge of the impermissibility of such an act, as the marketing employee receives a salary for his work and is not permitted to take a commission without the employer's permission.
