Transporting female students and teachers with a barrier in place of a mahram

The questioner:
Honorable Shaykh, this is Salim. He says: I want to work in the field of transporting female students and teachers, if I place a barrier between myself and them, such as a cloth or the like.

The Shaykh:
What?

The questioner:
He says: I want to work in the field of transporting female students and teachers. If I place a barrier between myself and them, such as a cloth or the like, am I required to bring a mahram (a relative one may not marry) to be with them?

The Shaykh:
As for travel, it is not permissible for them to travel except with their mahrams, as the Messenger of Allah (peace and blessings be upon him) said: except with a mahram. However, if it is not travel but within the city, there is no harm in you transporting a group of teachers or students, because this is not travel and it is not seclusion; this is not travel and it is not seclusion. But if you have a woman from among your mahrams with you, that is more complete and better, because if he needs to speak to you or you need to speak to him, it will be through this woman.

May Allah reward you
