Ruling on leaving the Friday prayer and congregational prayer for one who has an offensive odor

The questioner says: My father is elderly and does not go to the Friday prayer. He says that he is ill. When I asked him about it, he said his illness is a bad breath with a foul smell. He said he does not want to harm people with this smell. Is it permissible for him to do this?
The answer is: Yes, this is a valid legal excuse. If he has severe bad breath with a foul smell and there is no means available to remove it, then it is an excuse, just as onions and garlic are an excuse. Bad breath can be very foul and may harm those around him, on his right and left. If this bad breath is severe and harms those around him, and he finds no medicine or remedy for it, then he is excused. However, if he finds a medicine or a remedy that removes it, he must do so so that he does not miss the Friday prayer and the congregation. But if he is unable to do so and no remedy is available, he is more excused than the one who has eaten onions, because the one who has eaten onions can stop eating onions and garlic, whereas this person cannot if he is unable to find medicine. There is no doubt that bad breath harms those around him if its smell is apparent. Likewise, armpit odor, if it is severe and cannot be removed by soap and medicine, even if he is treating it and it does not go away, this is also an excuse. But if he can remove it by washing, using perfume, or other medicines that remove its effect from the armpits, it is obligatory for him to do so so that he can pray with the Muslims. Likewise, the smoker must remove the effect of smoke from his mouth by all means he can, and he should not smoke close to the prayer so as not to harm those around him. If there is any residue, he should use what removes the remaining smell, such as medicines or things to chew, or anything else that removes his smell, so that he does not harm anyone. Yes. And smoking... is ugly and reprehensible and must be abandoned. It is not permissible to trade in it, either by selling or buying. But whoever is afflicted with it should fear Allah and seek Allah's help in abandoning it, and beware of its evil and calamity. As long as he continues to use it, he should be careful not to enter the mosque with its smell apparent; rather, he should use what removes the smell and strive until Allah cures him of its evil and until he finds a way to quit it. Yes.
The presenter: May Allah reward you. In truth, Your Eminence, many men are lax regarding having a pleasant smell when praying. Some of them come wearing their work clothes or clothes like what you mentioned, with a foul smell. So I do not know how you would advise them in this matter?
The Shaykh: It is obligatory for the believer to strive to have a pleasant smell. The Prophet (peace and blessings be upon him) loved perfume and used perfume, may peace and blessings be upon him. If he is able to use what removes the smell, let him do so. But in the case of work, he may not be able to, so let him fear Allah as much as he can. However, if he is able to remove the foul smell, whether from smoke, armpits, or bad breath, let him fear Allah and work so that he does not miss the Friday prayer or the congregation. Yes.
