Q: What is the ruling concerning someone who totally denies Sihr?
Answer: The Holy Qur’aan makes explicit mention of the reality of Sihr. “And they used to teach people (the art of) “Sihr” (witchcraft).
A person who denies Sihr, denies an Aayat of the Holy Qur’aan. You can come to your own conclusion if denial of the Holy Qur’aan necessitates renewal of Imaan. Moulana Thanvi Rahmatullahi alayh said that Ulama don’t make people Kaafirs, they merely inform them that they have lost their Imaan. No one makes a murderer. A person is labeled as a murderer due to his actions. Similarly a person is labeled as a Kaafir due to his statements and actions.
