What is the legal ruling on paying a bribe to some employees to reduce the price of a shop that the tenant wishes to buy, knowing that the shop is legally his right?

If the lease contract specifies a known duration, the owner is not permitted to terminate the contract before its end unless with the tenant's consent. However, if the contract does not specify a known duration, it is invalid, and the owner may reclaim the premises and sell it. One must repent from paying bribes to employees to lower the price. If the sale occurred without the owner's consent, or through deception and fraud, it is invalid, and one must seek the owner's forgiveness or pay the remaining due price.
