Is the father's work in the accounting department of an Egyptian insurance company, and the resulting salary, pension bonus, and trade based on this salary, considered permissible or forbidden? And how can he absolve himself of this?

Working in commercial insurance companies is forbidden (haram) and must be stopped immediately, unless there is a necessity, while searching for a permissible job. The salary earned from this work is not permissible to benefit from, and must be spent on charitable causes and for the benefit of Muslims, unless the worker was compelled to work or was ignorant of the ruling before knowing of its prohibition; in that case, he may benefit from what has passed. Working in commercial insurance companies is forbidden because it involves ignorance (جهالة), uncertainty (غرر), gambling (ميسر), and consuming wealth unlawfully, and it constitutes cooperating in sin.
