Treatment of the evil eye with cup washings and the Shari'ah-based treatment

Question:
Honorable Shaykh, may Allah grant you success. Some people take from the eyes what they call "cup washings" or what remains from the date pits, then they wash it and drink it. Is this action considered valid?

Answer:
This is an expansion in treatment. It is obligatory to restrict oneself to what is supported by evidence, namely that the one who cast the evil eye touches the afflicted person and invokes blessings for him, as the Prophet (peace and blessings be upon him) commanded Sa'ad ibn al-Harith when he was afflicted by the evil eye. He ordered the one who had cast the evil eye to invoke blessings upon him, saying: meaning he invoked blessings for him.
And Ibn 'Amir ibn Rabi'ah was afflicted by the evil eye, which struck Shahr ibn Hunayn, so the Prophet (peace and blessings be upon him) ordered him to invoke blessings for him with water, and he said (peace and blessings be upon him): meaning the person performs wudu, washes with the water of his wudu, and pours it on the afflicted person, and he sends his clothes that are next to his body, such as the lower garment and trousers. And the shirt is washed and poured on the patient. This is the treatment.
As for taking the cups, taking the date pits, and taking this expansion, and taking the earth from the ground he walked on. All of this has no evidence for it. And it is an expansion in treatment. Yes. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad and upon his family and his Companions.
