The one who offers sacrifices to the jinn is not a Muslim
Question

                If a person dies who offers sacrifices to the jinn, and he persisted in doing so, can the funeral prayer be prayed over him or du’aa’ be made for him?
Praise be to Allah.It is not permissible to offer the funeral prayer over 
          him, or to wash him, or to shroud him. He cannot be considered to be 
          one of the Muslims and he should not be buried with them, because he 
          is a mushrik. The same applies to one who prays to the jinn or to the 
          awliya’ (“saints”) or to the occupants of graves, or offers sacrifices 
          to them. We seek refuge with Allaah.
