Is it permissible for a company to use an individual (residential) internet subscription priced at 200 Qatari Riyals, obtained in the name of an employee residing within the company's premises, and then extend its connections to the company's offices, instead of using the institutional subscription priced at 600 Qatari Riyals, in order to save 400 Riyals per month?

The fundamental principle is that whoever leases something through a valid contract owns its usufruct, and has the right to dispose of it as an owner, as stated in the Fiqh Encyclopedia. Leasing has foundations and regulations: adherence to conditions deemed valid by Sharia (definition), avoidance of harm to the leased item, and observance of custom in its use. The lessee must use the leased property for its intended purpose, abiding by the conditions or custom, and is entitled to benefit from the contracted usufruct or less, but not more than what was agreed upon. It is not permissible for companies to register under the name of an individual employee, as this involves deception and a violation of terms, since companies' use differs from individuals' use, which affects the rent.
