I have been using a hairbrush made out of boar bristles which is supposedly good for the hair. At first I had no idea what boar even was, I didn’t even assume it was an animal. I did my research and to my dismay and surprise, boar ended up being a type of khanzeer. Was it najes everytime I used that brush? And did I break my wudhu when using it? We’re all my prayers invalid? And Since I really had no idea, will it be held against me all those times I used it?
