What is the ruling of Islamic law concerning "Zar" ceremonies, which are held to expel jinn and devils, and which some consider a religious custom, despite the presence of practices within them that contradict Islam, such as not invoking blessings upon the Prophet (peace be upon him) and not supplicating to Allah for the patient's healing?

Zar is a type of deception and sorcery used by charlatans to treat those they claim are afflicted by jinn. They hold boisterous ceremonies where the patient and participants dance in a place filled with incense, sometimes chanting incomprehensible words. This act is an reprehensible innovation (bid'ah munkarah) that is impermissible to perform, attend, or remain silent about, as it involves polytheistic practices (shirk) and violations of Islamic law. Muslims must warn against this evil and advise other Muslims, especially those with weak intellect, guiding them to the legitimate Islamic treatment for jinn possession through the Quran and authentic supplications, seeking refuge with Allah, fortifying themselves with dhikr (remembrance of Allah), and consistently performing supererogatory acts of worship.
