Is it permissible for a committed Muslim woman to work in a school affiliated with a church in Syria, where both Muslims and non-Muslims study, and which is closed on Sundays?

It is not permissible to enroll Muslim children in schools that have bad objectives. Their guardians must be advised to transfer them to schools where their thoughts will be safe from negative influence. Similarly, it is not permissible for a Muslim man or woman to work in such schools due to what may result from that, such as aiding in evil or deceiving the Muslim masses. And whoever gives up something for the sake of Allah, He will compensate him with something better.
