Is it permissible for an employee to obtain medicine receipts from the pharmacy under the name of a different medicine in exchange for medicines she received from the doctor without a receipt? And is it permissible for her sister to submit her treatment prescription to the department where their father works to receive half of the costs?

An employee must be honest and truthful in their work, and avoid unlawful gains, lying, and cheating. The default is that medicine is available in pharmacies. If a specific medicine is not available, it is not permissible to lie or deceive to obtain it. If the medicine is only available from the doctor, it must be sold with an invoice, or the matter should be referred to the authorities. It is not permissible for children to request half the cost of treatment unless it is based on what they actually paid and supported by authentic documents.
