All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
It is possible that the mother affects her daughter with evil eye; rather, it is possible that a person affects himself with evil eye.
However, one should not have the audacity to say that it is the mother who affected her with evil eye without evidence.
In any case, that girl should look for tangible causes of what happens to her, and consult trustworthy doctors in compliance with the advice of the Prophet about seeking treatment.
She should not confirm that it is her mother who afflicted her with evil eye without evidence or strong indication.
In case her mother's looks bother her, then she should speak to her in a soft and gentle manner and ask her to stop what harms her.
Allah Knows best.
