What is the ruling on the salaries of employees who are absent from work with the knowledge of their managers, and attendance is signed for them, while work continues? Do they have to donate the value of the days they did not attend, and how is this value calculated?

It is not permissible to be absent from work unless authorized by the manager, provided that the presence of those available is sufficient to complete the tasks. In the event of absence without permission, it is not permissible to take wages for the days of absence, and what was taken must be returned to the workplace or given as charity. The value of a day is determined by consulting the relevant authorities or by calculating the full salary and dividing it by the number of days in the month.
