The Shaykh is the doctor who removes the cataract from the eyes of the spiritual heart, after which the Saalik is blessed with baseerat (spiritual sight) and Ma`rifat of Allah [swt] Ta’ala. And naturally, having recognized the Beloved, the goal is achieved.

By Hazrat Maulana Abdul Hamid Ishaq DB

We are told that if we suspect anything like sihr (witchcraft) or jinn, then Ayatul Kursi and the 3 Quls suffice from all harm and mischief.
