Does wudu protect against unintentional envy?

No evidence has been found to support the validity of this matter, but ablution (wudu) or ritual bathing (ghusl) is prescribed to ward off the harm of the evil eye after it has occurred. The person who cast the evil eye (al-'ain) is commanded to perform ablution, and then the afflicted person is to be washed with the water used by al-'ain for ablution, as the Prophet, peace and blessings be upon him, did in the incident of Sahl ibn Hunaif with 'Amir ibn Rabi'ah. The evil eye is real, and "if you are asked to wash, then wash." "Washing" (al-istighsal) means that the person who cast the evil eye washes the inside of his lower garment with water, and then that water is poured over the afflicted person.
