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.
You do not appear to be extreme in what you have mentioned; rather, you are right - Allaah willing. A woman is prohibited from travelling without a Mahram whether the distance of travel is long or short. For more information, please refer to Fatwa 88562.
The necessity of having a Mahram is even more stressed in the cases which you have mentioned and a woman is obliged to be careful from going out to a place where she could be harmed. Allaah says (what means): {…and do not throw [yourselves] with your [own] hands into destruction [by refraining].} [Quran 2:195]
Moreover, Ibn ‘Abbaas narrated that the Prophet
said: “There should be no harm nor reciprocal harm.” [Ahmad]
Allaah Knows best.
