If the person who put the evil eye on another is known, and some water that he has used for Ghusl or Wudu is taken and poured over the one who has been affected, that water may cancel out the effect of the evil eye and heal him by the permission of Allah (SWT).
A vessel of water should be brought to the man who put the evil eye on another. He should put his hand in it and rinse out his mouth, then spit it out into the vessel. Then he should wash his face over the vessel. Then he should put his left hand in and pour water onto his right hand over the vessel. Then he should put his right hand in and pour water over his left hand once. Then he should put his left hand in and pour water over his right forearm, then put his right hand in and pour water over his left forearm. Then he should put his left hand in and pour water over his right foot, then put his right hand in and pour water over his left foot. Then he should put his left hand in and pour water over his right knee, then put his right hand in and pour water over his left knee. All of that should be done over the vessel. Then he should put the top of his Izaar (or the waistband of his trousers) into the vessel. The vessel should not be placed on the ground, and it should be poured over the head of the man who was struck by the evil eye, pouring it in one go from behind. /p> (Sunan Al-Bayhaqi, 9/252)
If it is not known who put the evil eye on a person, then the one who has been affected has no recourse but to turn to Allah (SWT) by reciting the Dhikrs and Ruqya’s that are prescribed in Sharia, for there is healing in them if Allah (SWT) wills.
The sick person should hold their hands up together and recite into them:
Al-Faatiha (Al-Quran, Chapter 1)
Ayat Al-Kursi (Al-Qur’an, 2:255 )
Surah Falaq (Al-Qur’an, Chapter 113)
Surah Naas (Al-Qur’an, Chapter 114)
Blow into their hands and wipe them all over his body. The sick person may also recite these verses over olive oil and smear it on the site of pain, and he may wash and drink from that water.
