What is the ruling on an internal agreement with the property owner to raise the rent value in the contract for the employer to benefit from service bill allowances, in exchange for the owner undertaking to pay the bills, and what are the consequences for someone who has done so previously?

The employer must be informed of the truth of the matter, and there should be no deception to take what the company has not authorized. If the rent of the house is 900 pounds, it is not permissible to write it as 1200 pounds. Truthfulness leads to righteousness, and lying leads to wickedness. Registering information contrary to reality is considered a lie, deception, and a stratagem to unlawfully consume wealth, and it is forbidden, based on the Almighty's saying: (O YOU WHO HAVE BELIEVED, DO NOT CONSUME ONE ANOTHER’S WEALTH UNLAWFULLY), and the Prophet's (peace be upon him) saying: (WHOEVER DECEIVES IS NOT OF ME). Whoever has done this previously must return the money they took and did not deserve to the company.
