Islamic teachings emphasize the importance of maintaining modesty, safety, and protection for both men and women. While it is not obligatory for a woman to travel with a mahram or a trusted companion, it is generally recommended as a precautionary measure. Traveling with a close relative or a trusted companion can provide additional support, security, and companionship throughout the trip. The decision can vary based on individual circumstances, and it is advisable for a woman to seek guidance from knowledgeable sources before making a decision.
