The Ruling on Smoking During the Day in Ramadan

Question:
Sa'd from 'Arar has two questions. The first question, O Sa'd. Peace be upon you. And upon you be peace. In the name of Allah, if you please, a word from the Shaykh. Please, please. The first question, O Shaykh, may Allah reward you with good. My father is old and has chronic illnesses, and he uses this tobacco. I go to an area far from us, a distance of one hundred and fifty kilometers. And I am fasting. And as we are walking, he keeps smoking; he cannot refrain from smoking. Is there harm in that? He smokes during the day in Ramadan. He has diabetes and high blood pressure. Okay, okay, I will tell you: he smokes during the day in Ramadan? And as we walk, sometimes he says, "My mouth is dry," and drinks water, and sometimes he prepares [tobacco]. His father is old.

Answer:
If he intentionally drinks water, or smokes—meaning he smokes what is called tobacco—then that invalidates his fast, because he has introduced something into his stomach from the things that break the fast. Yes.
