Is it permissible to seek the help of jinn and to treat oneself with the Qur’an by drinking it, hanging it, and washing with it, in the case of being afflicted by sorcery?

Seeking help from jinn is not permissible in forbidden matters such as magic and harm, or if it leads to abandoning a religious obligation or committing a forbidden act. This is by scholarly consensus. As for seeking their help in permissible matters, there is a difference of opinion: some scholars prohibited it out of fear of doctrinal harm and polytheism, citing that Imam Ahmad disliked it, and العلامة Muhammad ibn Ibrahim considered it a request from the unseen, similar to asking the dead, and containing a scent of polytheism. Sheikh Ibn Baz said that it is a means to worship them and believe in them. Whereas Sheikh Al-Islam Ibn Taymiyyah permitted it if it was for permissible matters and did not exceed religious boundaries, considering the one who does so like someone who uses humans in permissible matters. In most cases, dealing with jinn leads to forbidden acts that may reach polytheism.

As for treating with the Quran by writing it and drinking it or washing with it, it is permissible due to the generality of Allah’s saying: "And We send down from the Quran that which is a healing and a mercy to those who believe," and His saying: "Say, 'It is for those who believe, a guidance and a healing.'" This has been permitted by Ibn Abbas, Ibn Taymiyyah, and others.

However, hanging amulets from the Quran on the body is not permissible, according to the preponderant opinion.
