Is it permissible for a doctor suffering from a chronic illness, who is taking sedatives and antidepressants, and has a medical recommendation to avoid staying up late and stress, to ask a colleague to cover his shifts in the reception and emergency departments in his stead, for a financial amount greater than the official remuneration for the shift, in order to avoid submitting an official medical report that might affect his reputation?

The doctor mentioned, in his work in the reception and emergency departments, is considered a private employee (ajir khass). He is required to perform the work himself, and it is not permissible for him to delegate someone else to do it, because the contract is based on his personal services. This is in contrast to a joint employee (ajir mushtarak), who is permitted to assign others to perform the work, unless it is stipulated that he must perform the work himself.
