All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
We have already issued Fatwa 91008 clarifying what the scholars determined that it is not permissible for a Muslim to take a means to bring benefit or repel harm except what is confirmed in the Sharee’ah or by experiment that it is so. Shaykh Saalih Al-Shaykh says: “The beliefs of the people in repelling evil eye are uncountable. To conclude, anything that the people do which they think that it is a means (of treatment) whereas it is not legislated in Sharee’ah nor decreed by Allaah to be so (a means of treatment), then it is not permissible to take it as such.”
Besides, the things that you mentioned in the question do not cure magic and evil eye, neither from an Islamic point of view nor from an experimental point of view. Rather, they are superstitions and illusions and a means of shaking the creed of Tawheed (worshipping Allaah alone). Moreover, this could be Shirk [associating partners to Allaah] if it is used to get closer to a jinn and the like. Therefore, one should avoid it.
It is enough for a Muslim to follow the commands of Sharee’ah.
For more benefit on treating magic and evil eye, please refer to Fataawa 82648, 85883 and 82918.
Allaah Knows best.
