Exploiting it by traveling to the lands of disbelief, which is forbidden.

The Shaykh : Are these four categories or five? No, four. The fifth is: the one who travels to the lands of the disbelievers. This is the most dangerous of all. The lands of disbelief are lands that have been destroyed of faith. You do not hear the adhan or the iqamah in them. Rather, you hear the bells of the Christians and the trumpets of the Jews. You do not hear in them. How is it fitting for a believer to go from lands where the greatness of Allah and His oneness are proclaimed to lands where this is not heard?! Along with the evil that is seen in their markets, cafes, restaurants, and hotels. And unfortunately, some people go with their families, and the young ones imprint this false image in their minds and never forget it. And this travel to the lands of disbelief is closer to being forbidden than to being permissible. Some of our contemporary scholars have explicitly stated that it is forbidden, even if the person is among the most pious of people, because a person is a human being and Satan flows through the son of Adam like blood. So beware of traveling alone or with your family to the lands of disbelief! Fear them, stay far away from them; there is no good in them or in their people. And among the people, and they are the sixth, is: the one who stays in his land, in his shop, his father's shop, in his farm, in his livestock. These people are in a good state as long as they do not commit a forbidden act in this sitting.
I ask Allah the Exalted to preserve our religion for us, and to reform our young men and women, our elders, and our middle-aged people, for He is capable of all things. And now, to the questions. We ask Allah to grant us success in them to the truth, for He is capable of all things.

The questioner : May Allah reward our father and our shaykh with the best reward, and benefit us all with what we have heard.
