A muslim reports his brother is hearing voices, drinking, walking down the street naked and asks for advice. A fundie replies:

That is extremely frustrating; a mental institute would be the inevitable outcome if the problem is jinn related and is diagnosed by a non-muslim...

Another commenter says:
Maybe you could visit your brother with a raqi and he could do ruqyah on him where he is. If it's jinn related, being in a psychiatric ward will just make it worse.

Another:

Is he in a hospital with Muslim staff?. If not you should explain that he is seeing Jinns and what Jinns are.

A FSTDTer may have invaded this board. He says:
There is no such thing as Jinn. All were destroyed when God destroyed the nephilim .
