The obligation of a patient suffering from bad breath in the mouth

We move on to another letter and other topics. The first of these letters is from a brother who says: (Dr. F. L. B.), an Egyptian resident in the Kingdom. Our brother complains of bad breath, and he also complains about his situation in prayer, as well as in Hajj and 'Umrah. Does he commit a sin if he goes to the mosque, or if he performs tawaf and sa'y while in that condition? Please inform us, if you please, O Shaykh.

Answer:
This matter may occur for some people. It is obligatory for him to focus on the causes that remove it, through treatment and taking medication, and by presenting his case to specialized doctors, so that he may find a cure that removes this bad breath, which may cause discomfort to those who sit near him. So, if he is unable to do so and treatment is not available for him, and if it harms the praying people around him and causes them discomfort, he has an excuse to pray in his home. Just as the Prophet (peace and blessings be upon him) prevented one who had eaten garlic or onions from praying with the people, and he used to send them out of the mosque, may peace and blessings be upon him, so that the Muslims would not be harmed by it. He (peace and blessings be upon him) said: And he said: .
So, the conclusion is that if this bad breath is severe and causes discomfort to those who sit near him in the mosque, he is excused from leaving the congregation and praying in his home, after he has exerted himself in seeking treatment and the means to remove it. If he is unable to do so, he is excused.
As for Hajj, no. Hajj is performed by everyone. Hajj is performed even if one has this condition. He performs Hajj and 'Umrah, and he is not required to be in close contact with anyone in this regard. In the crowd, he is like others; his crowding with people in tawaf, or in sa'y, or in stoning the pillars does not cause harm. We do not see this as an excuse in Hajj or in 'Umrah. This is only for the congregation specifically, the prayer of the congregation specifically. Yes.
The presenter: And regarding visiting, O Shaykh?
The Shaykh: As for visiting, this is different. If the person being visited permits it and is not harmed by his visit due to his kinship with him, or his friendship with him, or other reasons, then there is nothing wrong with it for him.
But if the person being visited is harmed by it, he does not visit. He does not visit him, but rather he seeks to fulfill his need through other means, such as writing, the telephone, or sending a representative to handle the needs he wants to address directly with that person.
The presenter: May Allah reward you.
