Renting out the musta'min (non-Muslims granted safe conduct) and workers in specific locations

The questioner:
Honorable Shaykh, may Allah preserve you. In lands other than this one, is it permissible to rent to non-Muslims granted safe conduct and workers, where there are no regulations in those lands to confine them to specific locations?

The Shaykh:
I?

The questioner:
In lands other than this one, is it permissible to rent to non-Muslims granted safe conduct, where there are no regulations to confine them to specific locations?

The Shaykh:
It is not befitting to allow them to spread among the families and among the Muslims. It is befitting that they be in a separate area. It is befitting for the Muslims not to allow them to spread among them, because they do not have faith. However, if they are under a treaty and own houses, we do not expel them from their houses, even if they are adjacent to the Muslims, because they are their property and we have made a treaty with them that they will remain.
