` Abdullah ibn Mas`ud reported, “Anyone who goes to a diviner, a practitioner of magic or a soothsayer, asking something and believing in what he says, denies what was revealed to Muhammad.” (Reported by Al-Bazzar and Abu Ya`la). The Prophet (peace and blessings be upon him) said, “Whoever blows on knots practices magic, and whoever practices magic is a mushrik (polytheist).” (Reported by At-Tabarani) As for the Islamic legal status on practicing black magic, it is forbidden, and this makes one’s prayer unaccepted for forty days, and believing in what magician or sorcerer says renders one a disbeliever.
Generally speaking, it should be demonstrated that black magic is one of the well-established facts, and it is mentioned in the Qur’an and the Sunnah.
