Ruling on attending the mosque for one who has eaten garlic and onions

Question:
Is it disliked, O Shaykh, or is it forbidden?

Answer:
This is what one should attend. The apparent indication of the prohibition is that it is forbidden; it is not permissible for him to attend while he has the smell of garlic and onions. As for eating garlic and onions, it is permissible. If there is a need for it, he may eat it, but he should not attend the congregational prayer.
Q: Is it forbidden?
A: No, it is not forbidden, but it is not permissible for him to attend the congregational prayer until the smell goes away.
Q: Why does he not attend the congregational prayer?
A: Because of its bad smell.
Q: The statement of 'Umar (may Allah be pleased with him) : "Whoever wants to eat them, let him cook them"?
A: It means: if he needs them, he should cook them.
Q: Does fire remove the smell?
A: It lightens the smell. As for onions, the smell goes away, but garlic may remain to some extent. However, if he makes a strong effort to cook it, it may go away, or he may take some medicine that removes the smell.
