I am asking this question on behalf of my friend. It is regarding Bribery. She was house hunting and found a house she really liked, however the house had alot of interest, so the agent told her to give her some money under the table and he ll ensure she gets the house. Which means, the agent will by any chance pass only my friend’s offer to the house owner. Is this permissible?

The agent is not representing his client in the client’s best interest, I would totally abstain from such a transaction.
