What is Ruqyah in Islam, what is recited in it, what are its benefits, and how is it performed?

There are several books that can be referred to for more information about Ruqyah Shariah and its benefits, including: "Al-Ruqyah Al-Shariah" by Dr. Khalid Al-Jeraisy, "Healing with Ruqyah from the Qur'an and Sunnah" by Dr. Sa'eed Al-Qahtani, and "Al-Ruqyah Al-Shariah from the Qur'an and Sunnah" by Ali Al-Faqihi.
