Black Magic: Rulings & Remedy - IslamonLine.net - Ask The Scholar
Sheikh `Atiyyah Saqr, former head of Al-Azhar Fatwa Committee, adds:
1- Magic has been known as a well-established fact regardless of it changing the forms of things.
2- Magic involves things that may be beneficial or harmful, as Allah says: “learned from these two, magic by which they might cause a separation between a man and his wife…”
3- Magic cannot have any effect save by the Will of Almighty Allah, as Allah says: “…and they cannot hurt with it any one except with Allah’s permission…”
4- Adhering to magic renders one a disbeliever, as Allah says: “…but the Shaitans disbelieved, they taught men sorcery…”
The views of Muslim scholars carry culminate in the following:
1-Attributing the effect of the magic to anything other than Allah renders one a disbeliever.
2-Practicing magic or sorcery for the sake of harming people is totally forbidden. Based on this, it is a form of disbelief to torture people with a magic spell or subject them to the evil of jinn.”
