Does injecting blood into the body, or drawing it for analysis or donation, invalidate the fast?

The questioner:
May Allah reward you and bless you. This questioner asks about the ruling in the following case: a person had blood drawn from him for analysis or donation; what is required of him?

The Shaykh:
If the blood is a small amount drawn for analysis, it does not harm the fast. However, if it is a large amount drawn for analysis or donation, it breaks the fast; because it is like cupping. It is established in the authentic hadith that cupping breaks the fast of the one who is fasting, and this is like it.

The questioner:
The second paragraph says: A person was given blood from a donor for his need.

The Shaykh:
Likewise, if he is given blood that is injected into him, this invalidates the fast; because it is in the position of food and drink; because it nourishes the body. If the fasting person is excessive with blood [infusion], it invalidates his fast; because it is like eating and drinking, it nourishes the body and strengthens it. Yes.
