What is the ruling on a female teacher's absence from work due to menstruation-related illness, given that she obtained a medical leave certificate from the hospital through her acquaintances without seeing a doctor, and is her action considered a lie and a deception?

The physician grants sick leave after examining the patient. Obtaining it without a physician's examination is considered a lie and deception, and it aids the physician in lying. However, if the employee is suffering from an illness that necessitates rest, and the physician was previously aware of their medical condition, then the employee is permitted to be absent and take sick leave, even if they do not go to the hospital.
