Is it permissible for someone who has eaten onions or garlic and then used something to conceal their smell to pray in the mosque?

The prohibition in the hadith against those who have eaten garlic, onions, or leeks from praying in the mosque has been interpreted by many scholars as a disfavor (karahah), because the angels are bothered by what bothers humans. If, after eating them, one consumes something that removes the odor, such as mint, parsley, cardamom, or certain types of chewing gum, then there is no harm in coming to the mosque, as the cause of the prohibition, which is the nuisance, has been removed.

Eating garlic, onions, and leeks is permissible (halal), and the prohibition concerning them is only due to their unpleasant odor. If one eats them not with the intention of missing congregational prayer, and the odor is gone, then there is no harm in going to the mosque. However, if the odor persists, then it is not permissible for a Muslim to enter the mosque.
