Can you summon Jinn that grant wishes?

I mean..potentially you might find information on the subject, or purchace ritual objects for such a summoning; but you don't really go there to find a witch to do it for you. The employees try to be helpful where they can, but they won't do it for you. The rituals they do provide are generally limited to what's listed on their event page

This is a book store.

As a Muslim I don’t recommend you doing anything with Jinns. They don’t grant wishes, there’s nothing good that comes out of summoning one. They are kind of the same as devils in Christianity just much worse so yeah I wouldn’t recommend you summoning a Jinn.
