Ruling on traveling to Islamic countries where there is free mixing of men and women

Question:
What is the ruling on traveling to Islamic countries where free mixing between men and women is prevalent? May Allah reward you with the best reward.

Answer:
It is not permissible to travel to the lands of the disbelievers, because it contains an immense amount of evil that cannot be counted. Therefore, it is not permissible to travel to the lands of the polytheists. The scholars have explicitly stated this, and the Messenger (peace and blessings be upon him) said:
Traveling to the lands of the polytheists involves great dangers, except in cases of extreme necessity, such as seeking medical treatment when necessary. A group of scholars have permitted this out of necessity, provided one is cautious and stays away from the causes of evil. It is also permissible for a scholar who calls people to Allah, who invites them to Allah and teaches them good, and who is a person of knowledge and insight, and one who does not fear fitnah (trial, discord or temptation). There is no harm in this if he knows his religion, displays his religion, and calls to Allah.
