Is it permissible for an employee with viral hepatitis, who has been suspended from work by his company with a year's salary for treatment, to submit invoices for a treatment approved by the company without actually taking it, and instead take another medication at his own expense, in order to obtain the costs of the medication approved by the company, especially if the company-approved treatment is harmful to him, and the alternative treatment leads to healing, Allah willing?

If it is established with certainty or a strong probability that the prescribed medicine is harmful, then it is not permissible to take it, based on the Almighty's saying: "And do not kill yourselves. Indeed, Allah is ever Merciful to you." The company must be informed of this matter to dispense another suitable medicine. If that is not possible and there is no alternative but to submit invoices bearing the name of the substituted medicine, then there is no objection to doing so to avert harm.
