What is the ruling on a woman traveling without a mahram due to an urgent necessity? Thank you.

A woman is not permitted to travel without a mahram (definition) (unmarriageable kin) according to Islamic law, based on the Prophet's (peace be upon him) saying: "It is not lawful for a woman who believes in Allah and the Last Day to travel for a distance of a day and a night except with a mahram." Exceptions to this include dire necessity, such as being in an unsafe place, or migrating from a land of disbelief to a land of Islam. Some scholars have also included travel for Hajj and Umrah (definition) with a trusted company, classifying this under the necessities that permit the forbidden.
