Is the same ruling applied if a person has a foul odor?

The Shaykh : Now, is the same ruling applied if a person has a foul odor, or if there is a bad smell in his mouth, nose, or armpits? The scholars said that it is the same, because this is to repel his annoyance. You find some people who do not care about themselves; they do not wash or clean themselves, and they have a foul smell that can knock birds down. The story of the women in the pre-Islamic age of ignorance has passed you by, where they rarely used a deodorant without the person dying from the foul smell. Some people swear to me that they can never stand the side of some others who do not care about themselves. We also say that it is forbidden to enter the mosque. The scholars said that if such a person is found in the mosque, it is permissible to remove him from the mosque.
