All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
If the amount of money which the company is going to pay you in return for accommodation will be given to you in totality regardless of how much you indeed are going to pay, then there is no harm in what you have mentioned. However, if the company gives this amount as a maximum for rent and if the rent is less than the amount given to you, the company will not pay you more than the amount of rent, and whatever remains will be given back to the company, then you are not permitted to do what you mentioned. The evidence is that the Prophet said: "The Muslims should fulfil their conditions.'' [Ibn Maajah]
Finally, we draw the attention of the questioner, the company and others, that the terms of the contracts should be well defined so that the transactions will be well established in order to avoid any disputes. If the contracts are conducted while the rights and obligations of both parties are not defined, then this is cheating and deceiving and this is something which Islamic legislation denies and rejects.
Allaah Knows best.
