Is it permissible to move out if family members are also sick in current location?

الاستفتاء

The people in our home are always sick. When one sickness passes, we are afflicted by another. Most of our relatives have advised us to leave this house. One has also said that he has done Istikhara on our behalf, so we should move out. My mother also had a dream of my grandmother telling her to leave this house and find a new one. Our family is very concerned about this matter. Please advise us what to do. Is this happening because of black magic? Please tell us a way to relieve ourselves from this problem.

الجواب حامدا و مصلیا

In the name of Allah, the Beneficent, the Merciful
It is not ideal to make a decision based on a dream. The family should consult with a religious Aamil and find out whether or not their current home is affected by Jinns, black magic, etc. since this can be possible. If the Aamil says that changing their home will relieve them from this problem, then the family should move out and find a new place to live.
