What is the ruling on the prayer of someone who comes to the prayer with the smell of garlic and onions emanating from them, while the worshippers are aware of it?

It is disliked for someone who smells of garlic, onions, or other foul odors to attend prayers in the mosque due to the potential harm it may cause to the worshippers. Such a person is permitted to forgo congregational prayer if they cannot rid themselves of the odor. They should be advised gently and the truth explained to them.
