Do the symptoms the sister is experiencing—numbness, tingling, and body pains, and the inability to sleep continuously except with the sound of the Qur'an—necessitate Ruqyah Shariah, and which is better: for her to perform Ruqyah on herself or to go to a righteous raqi, and what are the correct methods of Ruqyah if she performs it on herself?

What afflicted your sister is likely to be sorcery or possession. The cure for this is through legitimate ruqyah (definition), coupled with frequent supplication, seeking forgiveness, reciting the Quran, maintaining daily remembrances (adhkar), and avoiding sins. It is best for the sick person to perform ruqyah on herself, following the example of the Prophet (peace be upon him), as indicated by the praise for those who do not seek ruqyah from others. However, it is permissible for her to seek ruqyah from people of piety and righteousness if her condition does not improve.
