Praise be to Allaah.
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.
