Breaking the fast intentionally: Is making up the fast required?

The questioner : Honorable Shaykh, she says: The legal principle is that time-bound acts of worship are not valid before their time or after it. So how do you order the one who intentionally breaks his fast for a day in Ramadan to make it up?

The Shaykh : Do you understand the question, everyone? We mentioned last night that if a person delays a time-bound act of worship from its time without an excuse, it is not accepted from him, and we do not order him to make it up, because making it up is futile. So he is asking now: How did you say this, while you order the one who intentionally breaks the fast to make it up? Do you know the difficulty or not? Well, we say that in reality, there is no difficulty. Because the one who started fasting was legislated to be committed to it, and this is like a vow; it is obligatory for a person to fulfill it. So when he started it, it became obligatory for him, obligatory for him. If he invalidates it by eating, drinking, or intercourse, we say it is obligatory for you to make it up, because by starting the fast, fasting became obligatory for you, so you are required to make it up. This is different from if he left fasting entirely, meaning he said to himself, "I will not fast on Wednesday because I am going on an outing," or "I will not fast because I have exercises on Thursday and I want to be energetic." Is this person ordered to make it up?
Why? Because he left fasting in the first place; he did not fast. It is as if he moved this day from Ramadan to a second time.
