Is it permissible for a man to teach female students without a hijab?

Question : A questioner says: I am an Islamic education teacher in one of the Arab countries, and I teach in a girls' school. There is no hijab between me and them. Is my work permissible?

Answer : If a male teaches males and a female teaches females, that is what sound fitrah (the innate natural disposition) and sound reason dictate. But if a person has no option but to teach women while he is a man, or a woman teaches men, then there are rulings for dire necessity. However, there must be a barrier that prevents the women from being seen and prevents the students from seeing the teacher, so that fitnah (trial, discord or temptation) does not occur. Then, if fitnah happens, whether through the woman's voice or otherwise, it is obligatory to abandon teaching in this situation, because protecting the religion is an obligatory matter. Satan flows through the son of Adam like blood. A person may enter into such works while confident in himself, but Satan will not cease with him until he tempts him in his religion. The Prophet (peace and blessings be upon him) ordered the one who hears about the Dajjal (the false messiah) to stay away from him, because a person may come to the Dajjal while confident in himself, and then the Dajjal will not cease with him until he makes him contradict his religion, so he follows the Dajjal. We ask Allah for safety. So you do not risk yourself in matters you fear...
