Is it permissible for the fasting person to consume these things that break the fast, or not, whether in voluntary, obligatory, or make-up fasting?

The Shaykh : Also related to our previous discussion is a matter we have not yet examined: is it permissible for the fasting person to consume these things that break the fast, or not? Is it permissible for the fasting person to eat or drink, or take nutritional injections, or undergo cupping, or the like, or is it not permissible? This is an important issue. We say: if the fast is voluntary, there is no blame on him if he consumes these things that break the fast and breaks his fast. Did you understand the answer? Yes or no? If the fast is voluntary, there is no blame on him if he consumes these things that break the fast and breaks his fast, because a voluntary fast is not required to be continued, so he may break it. However, the scholars said that he should not break it except for a valid purpose. The evidence for this—may Allah have mercy on you—the evidence for this is that the Prophet (peace and blessings be upon him) entered his house one day and asked about food that was on the fire, and he called for it and said to 'A'ishah: Then he ate. This is evidence that if a person is fasting a voluntary fast, it is permissible for him to eat and drink. Likewise, if one of those fasting is invited by a friend to a feast, whether it is a wedding feast or otherwise, and he attends, is it permissible for him to break his fast and eat and drink? Yes, especially if doing so brings comfort to the host. However, if the fast is obligatory, pay attention: if the fast is obligatory, it is forbidden to consume these things that break the fast, whether the obligatory fast is an expiation, or making up Ramadan, or for a ransom payment. The important point is that as long as it is obligatory, it is not permissible for him to consume these things that break the fast. Let us suppose a man is fasting to make up Ramadan, fasting to make up Ramadan; is it permissible for him to eat and drink? No, because when a person begins an obligatory act, it is obligatory for him to complete it except for an excuse.
