oh no lol... you fools are afraid of bacteria too? The vast majority of bacteria pose absolutely no threat to healthy humans and animals. I guess you don't eat cheese either. You probably fear the yeast too lol....
You probably think a muslims skin is pure and clean while you're praying to your god. What a joke. The reality is you have all sorts of little critters in your gut, in your mouth, on your skin and in your hair and there's not a fucking thing you can do about it.
I guess you're one of those white dudes, who takes a dump then wipes his ass with paper and goes back to work all day long.
Hygiene is very important in Islam. So yes, every time we pray we wash our hands, elbows, face, mouth, nose, ears, top of feet, etc...
I know America only recently discovered that washing hands after going to the bathroom or before eating is a good idea... but we knew this a very long time ago
