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, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
If you mean by “blue palm” a piece of wood (or ceramic) that is carved in the shape of a hand, colored in blue and inscribed with some Quranic verses and hung with the belief that it would protect against the evil eye or envy, then it would be impermissible.
Allaah Knows best.
