Is it permissible or forbidden to use a bullet dissolved in water over which the Quran has been recited to treat someone afflicted by the evil eye?

What is prescribed for someone afflicted by the evil eye or other ailments is the legitimate Ruqyah (spiritual healing) using the names of Allah Almighty, His attributes, His verses, and what has been authentically narrated from the Prophet, peace be upon him, as he said: “There is no harm in Ruqyah as long as it does not involve polytheism (shirk)."

For Ruqyah to be permissible, it must be with the words of Allah or His names and attributes, and in the Arabic language, and the one performing it must believe that Ruqyah does not have an effect by itself, but rather by the decree of Allah the Almighty.

Reciting the Qur'an over the afflicted person is prescribed, based on the saying of Allah the Almighty: "And We send down from the Qur’an that which is a healing and a mercy to those who believe."

As for melting lead in boiling water, it has no basis in religion and is not among the prescribed forms of Ruqyah.
