Does eating garlic, onions, or leeks prevent one from praying in congregation?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If a person eats garlic, onions, leeks, or the like, and the time for prayer arrives, is he prevented from praying in the mosque, or not? And what is obligatory for him in this state?

Answer:
Yes, he must refrain from going to the mosque, and he commits a sin by abandoning the congregation. He commits a sin by abandoning the congregation because he is the one who caused it; he is the one who caused not going to the mosque, so he commits a sin by abandoning the congregation.
