What is the permissibility for a student of knowledge to search for books on hypnotism and dealing with jinn from the Al-Futouh Astronomical Institute in Cairo, and would this request be fulfilled?

It is not permissible to guide your friend to a website that instructs and teaches its visitors how to deal with jinn, because this falls under cooperating in sin. Hypnosis is a form of sorcery, and dealing with jinn leads to seeking their help in sin or seeking their aid, especially with the prevalence of charlatanism, magic, and trickery in this era.
