Is it permissible for those with strong odors from various professions to skip congregational prayers?

It is disliked for someone who has an odor that bothers worshipers, and which cannot be removed, to attend prayer in the mosque. Such a person is excused from congregational prayer on account of this. The decisive factor is whether the odor is disliked or harmful, not merely its intensity. If the odor is pleasant or acceptable, then there is no dislike in it.
