Is it permissible for a woman to travel from one country to another without a mahram (a relative one may not marry) if she has no mahram?

The questioner:
May Allah reward you, my brothers. The father says: The questioner is a woman who has a relative who asks: Is it permissible for her to travel from one country to another without a mahram? Because she has no mahram, and her father is either absent from her or does not want to travel with her?

The Shaykh:
What is the ruling on travel? This travel is not permissible for her without a mahram. If she has no mahram, she stays in her house and does not travel until she obtains a mahram. If the travel is for Hajj, it is not permissible except with a mahram. The Prophet (peace and blessings be upon him) returned one of the warriors from a battle so he could perform Hajj with his wife. If this is the case for Hajj, what about other travel? Yes.

The presenter:
May Allah reward you. Your Eminence, the father, the questioner says:

The Shaykh:
They only mentioned this in the context of migration from the lands of disbelief to the lands of Islam, if she does not find a mahram and her remaining in the land of disbelief exposes her to leaving the religion. In that case, she travels even without a mahram, because this is a dire necessity.
