What is the ruling on undoing magic spells by means of magic?

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.

Undoing magic spells using magic is impermissible. They can be undone using lawful methods. For further information please read Fataawa 82918, 83618 and 91780.
