The ruling on the prayer of one from whom the smell of garlic, onion, or smoke emanates

Question:
Some of the worshippers are lenient in eating garlic and onions, and perhaps the smell of smoke is strong with them. So what is the guidance of Your Eminence for such people?

Answer:
One from whom the smell of smoke emanates and he harms people with it, or garlic, or onion, or leek, it is not permissible for him to pray with the people. The Messenger (peace and blessings be upon him) ordered that he be taken out of the mosque and said: "Whoever eats garlic or onion, let him not approach our mosque, but let him stay in his house." It is not permissible for him to pray with the people and harm them. He is not allowed to eat it in order to leave off the prayer, except if he has an excuse such as medicine or hunger. And if he eats for medicine or hunger, he does not pray with the people; he prays in his house until the smell goes away. And so the smoker does not pray with the people if the smoke is apparent, until he removes its effects. He is required to leave off smoking because it is forbidden. So he is required to leave it off, to guard against it, and to pray with the Muslims. If he fails to do so, he is wronging himself and disobeying through both the smoking and the absence. We ask Allah for well-being.
