What is the ruling on preventing some workers from entering the mosque because of their smell?

Question:
He says: Honorable Shaykh, may Allah grant you success. The imam of a mosque prevented some workers from entering the mosque to perform the obligatory prayers, citing their smell. He says their smell is repulsive, and he compares this to one who eats garlic and onions. We spoke to him about it, but he refused. What is the ruling on his action from the perspective of the Shari'ah?

Answer:
It is not permissible to do this; it is not permissible. It does not prevent what prevents the Muslims from praying, but it encourages them to be clean, or he should use incense or perfume in the mosque to cut off the smell of the workers. Yes.
