Do those who are currently taking from Muslims have support from Islamic law?

"Al-istirqa' (seeking ruqyah (definition)) is permissible, and many prophetic hadiths attest to it, such as the narration by 'Awf bin Malik: 'Present your ruqyahs to me; there is no harm in ruqyahs as long as they do not contain shirk (definition) (polytheism),' and Aisha's statement: 'The Messenger of Allah, peace and blessings be upon him, used to command me to seek ruqyah for the evil eye.' This does not contradict the hadith (definition): 'Seventy thousand of my Ummah will enter Paradise without reckoning... those who do not perform ruqyah, nor seek ruqyah, nor believe in evil omens, and upon their Lord they rely.' Imam An-Nawawi reconciled between them by stating that the praise for abandoning ruqyah refers to unknown ruqyahs or those containing shirk. As for ruqyah with verses from the Quran and known invocations (adhkar), it is permissible and a Sunnah (definition). Scholars have unanimously agreed on the permissibility of ruqyah with Quranic verses and remembrance of Allah the Almighty. The prohibition that was previously reported concerning ruqyah was either a prohibition that was later abrogated, or it referred to unknown ruqyahs, or to some people's belief in the intrinsic effect of ruqyah itself, rather than by Allah's permission. The hadith 'There is no ruqyah except for the evil eye or a sting' does not mean confining ruqyah to these two; rather, it implies that ruqyah for the evil eye and stings are more deserving and prioritized due to the severity of their harm."
