Assalamualaikum...i want to ask about watching videos of someone doing black magic,shirk,kufr for educational purposes and to create awareness....Is it still a major sin to watch videos of that if its for educational purposes and be aware of that things?As there is a brother who exposes the black magician or magic etc by making videos of that is it still a major sin?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

What appears to us - and Allah knows best - is that it is permissible to watch such videos in order to find out the truth about their falsehood, to avoid their evil, and to know their plots in order to beware of them. There is nothing wrong in watching falsehood for a valid purpose. There are examples mentioned in the texts of the Qur’an and Sunnah that tell stories of falsehood in order to show their falsehood, and among them is the magic of the magicians of the family of Pharaoh and their story with the Prophet of Allah, Moses, peace be upon him.

However, we warn you that watching this just for the sake of watching and to have fun and to spend time is not permissible. The Muslim jurists have a saying regarding this: Everything that is forbidden is also forbidden to be watched.

Allah knows best.
