The Effect of an X-ray Injection on Fasting

Question:
The questioner: Honorable Shaykh, may Allah grant you success, a person is fasting and then wants to get an X-ray at the hospital. They told him he must take an injection, which is a dye and not a nutrient, so that the X-ray images are clear. Does this injection break his fast?

Answer:
The Shaykh: If this is an obligatory fast, then he should avoid this thing; let him do it at night or after Ramadan. But if it is a voluntary fast, completing a voluntary fast is not obligatory; it is permissible to break it. It is permissible for him to break his fast, even if he is awake; it is permissible for him to break it, and he is not required to complete the fast. If it is a strange fast, then either he postpones this to the night or to after Ramadan. And if he is harmed by it, then he undergoes this examination and makes up this day later, because he has become ill, and it is permissible for the sick person to break his fast. Yes.
