All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
May Allaah bless you, accept your good deeds and increase your zeal in spreading and teaching Islam.
Dear sister, as long as your lessons require traveling a distance which is considered according to the customs of the residents of that area as traveling then all the rulings of traveling apply and thus should be adhered to. We think that the purpose of teaching Islam is not a necessity that permits you to violate Islamic rulings.

Allaah knows best.
