The ruling on taking a blood sample from a fasting person
Machine translationRead the Arabic original
Question:
The questioner asks: When a blood sample is taken, does it break the fast or not? For a woman who is fasting.
Answer:
A small sample does not harm; rather, it is this large amount of blood. A large amount of blood invalidates the fast when it is drawn from the fasting person, because this is like cupping. The hadith regarding cupping is authentic that it breaks the fast because it involves drawing blood. So likewise, a large amount of blood taken for donation or to treat a patient invalidates the fast, just like cupping. As for a small amount, it does not harm. Yes.
