How can one get rid of a hijab message containing talismans and magical claims to avoid any potential harm?

These talismans are magic and sorcery. To get rid of the message containing them, delete it from your device and recite the Mu'awwidhat (Surahs Al-Falaq and An-Nas) while deleting. You should also advise your friend to abandon these dangerous acts. If he persists, distance yourself from him.
