Answered by Shaykh Abdul-Rahim Reasat
If one hears of someone practicing magic by, for example, drinking blood, etc. then can we assume and say that they are disbelievers? Or should one refrain from labeling them?
The best thing to do is to ignore the matter if you don’t have any dealings or contact with the person. Many times people make lies up about others, or they are just stories based on misunderstandings.
It’s best not to worry yourself with stories about others. Follow the advice of the Prophet (Allah bless him and give him peace): “Be avid for what benefits you.” [Muslim]
He (Allah bless him and give him peace) also said, “Indeed, Allah dislikes for you three matters: gossip, wasting money, and excessive questions.” [Bukhari]
If you know the person in question, ask them if the matter bothers you. If he admits to practicing black magic or having commissioned someone else to do it for him then it’s best to distance yourself from him. Do not assume he is a disbeliever.
The Ruling of Black Magic
Some forms of black magic include practices that are disbelief, such as disrespecting the Quran or saying statements of Kufr. Anyone who does this leaves Islam due to those actions.
Other forms of black magic do not entail disbelief. Its practice is fisq (gross disobedience) but not disbelief. [Ibn ‘Abidin, Radd al-Muhtar] Drinking blood would be in this category.
Neither is good for one’s relationship with Allah, nor do they lead to salvation on the Day of Judgement. Avoid getting involved with those who engage in it.
May Allah grant you the best of both worlds.
