The ruling on using the remnants of one from whom the evil eye is feared

Question:
The questioner, your sister in Allah (F. Al-Sabaei), says in her first question: Some people, when someone comes to them from whom they fear the evil eye, wash the vessels from which this person drank after he leaves them, and they drink the water in which these vessels were washed, and wipe their faces with it. They believe that this removes what is attached to the evil eye, and that it does not harm them—if Allah wills—if they do this. What is your advice to such people, O Shaykh?

Answer:
I do not know of any basis for this. However, if someone is accused of having the evil eye, or it is known that he has the evil eye, he is asked to wash his face, his hands, the inside of his garment, and the tips of his feet, as mentioned in the hadith. Generally, if he washes his face and hands, that is sufficient. Water is poured on the one afflicted by the evil eye, and he is cured—with the permission of Allah—just as happened with Sahl ibn Hanif and 'Amir ibn al-Rabi'.
The point is: this is what is required if they know that this person cast the evil eye, or if they suspect that he cast the evil eye on this person; they ask for water so he can wash his face and hands, and it is poured on the one afflicted, and he is cured.
As for them washing the vessels after he leaves, I do not know of any basis for this, and I do not know. But if they accuse him of it and it is beneficial, there is no harm. If they accuse his family of having the evil eye, and they wash the vessel from which he drank and it is beneficial, there is no harm, praise be to Allah.

The presenter: May Allah reward you, O Shaykh.
