Manzil is a very good protection against Jinn and sorcery. Our Prophet Sallallahu 'Alaihi wa Sallam has taught us Dua for every occasion of our Religious and Worldly needs.
It has been mentioned in a Hadith from Abu Laila (RA) that I was sitting with Rasulullah Sallallaahu 'Alaihi Wasallam when suddenly a person came and said I have a brother in pain. The Prophet Sallallaahu 'Alaihi Wasallam said what is his pain? He replies junoon (madness/ insanity). Rasulullah Sallallahu 'Alaihi wasallam said, Go back and bring him with you. He came and sat in front of Rasulullah Sallallaahu 'Alaihi Wasallam and I heard him recite the following:
-Ta'awwuz (A'oozu Billahi minash-Sahitanir Rajeem)
-Surah Al-Fatihah
-1st four ayats of Surah Al-Baqarah
-2 ayats from its middle, wa ilaahukum ilaahu waahid
-Ayatul Kursi
-3 ayats at the end of Surah Al-Baqarah
-1 ayat of Surah Aal Imraan, shahid allahu annahu la ilaha illa huwa
-and recited an ayat of Surat-ul-A'raaf, inna rabba kumullahu...
-an ayat from Surah Mu'minoon, wa man yadu maallahi ilaahaan aakara la burhaan lahu bihi...
-and an ayat of Surat Jinn, wa annahu taalaa jaddhu rabbina ...
-and 10 ayats from the beginning of Surat-us-Saaffaat
-3 ayats from the end of Surat-ul-Hashr
-Qul huwallahu ahad
-and Mu'awizatain
Hence the person (who was insane) stood up and indeed he was free of it and there was nothing wrong with him (no annoyance). [Ibn Majah]
There are many Ayat of the Holy Qur'an that have some special effect if recited with conviction. Our Prophet Sallallahu 'Alaihi wasallam recited
wa ja'alna min-baini aydeehim saddan-wamin khalfihim saddan fa aghshainaahum fahum la yubsiroon when he left his house on the night of Hijrah, and his house was surrounded by young men of Quraish with naked swords in their hands, ready to kill him
na'oozubillah, and yet none of them was able to see him leaving the house. Moreover, he took a handful of sand and threw it on their heads.
Similarly, there are many ahadeeth that mention recitation of a particular dua for a particular ailment. So there is nothing wrong in compiling all the ayat used for treatment in one booklet, and naming it as Manzil.
And since there is no Shar'i ruling (Sunnah/Mustahab/Fardh etc) associated with the recitation of Manzil, there is no need to prove it from the
Nass (Religious texts). You may read it if you find it beneficial, or leave it.
Wallahu A'lam
