Nothing more harmful to the branches of knowledge

Reference: at Ta’aalam wa Atharuhu ‘alal Fikr wal Kitaab – Page 7

Ibn Hazam (rahima-hullaah) said:

There is nothing more harmful to the branches of knowledge and its people than those who enter themselves into it and they are not from its people. They are ignorant and yet they think they have knowledge, they cause corruption whilst thinking they are correcting the affairs.
