I was searching for Ways of Treating Magic. I found an answer in islamqa
It said we should read
"Surat al-Fatihah, Ayat al-Kursiy, Surat al-A’araf verse 106-122, Surat Yoonus verse 79-82, Surat Ta-Ha verse 65-69, Surat al-Kaafirun, Surat al-Ikhlas and al-Mu’awwadhatayn."
However, it did not mention Why these Ayats are used to perform Ruqyah.
As far I know "Surat al-Fatihah, Ayat al-Kursiy, and al-Mu’awwadhatayn" is very important to protect from bad stuff.
But I could not find anything regarding reading "Surat al-Kaafirun, Surat al-Ikhlas, Surat al-A’araf verse 106-122, Surat Yoonus verse 79-82, Surat Ta-Ha verse 65-69" to perform ruqyah.
Can you please give reference to these Surahs and Ayats to be recited to perform ruqyah. Or, at least explain when these Surahs and Ayats are prescribed by the sheikhs to perform ruqyah or cure Magic.
Upon further reading on alifta.com, I found that
All the Glorious Qur'an is blessed and can be recited as Ruqyah. Al-Fatihah (Opening Chapter of the Qur'an), Ayat-ul-Kursy, Surah Al-Ikhlas and Al-Mu`awwidhatayn can be recited as Ruqyah
I am still to find out why Surat al-Ikhlas and Surat al-Kaafirun are specifically prescribed for Ruqyah.
