These are 33 verses of the Qur’aan which eliminate the affects of Magic and become a means of protection from Shayateen, thieves and harmful beasts and animals. (Shah Wali-ullah (RA): AlQawlul- Jameel)
Maulana Muhammad Talha s/o Hazrat Shaykh Maulana Zakariyya (RA) Says: “These are verses of the Qur’aan which are known as “Manzil” in our family and elders of our family used to practise/read these assiduously and ensure that all the children learned them in their childhood.

This is from Shah Wali-ullah (RA) and not Shaykh Maulana Zakariyya (RA) as people misunderstand.
