The Effect of Blood Draw for Analysis on Ablution and Fasting
Machine translationRead the Arabic original
The questioner:
The questioner says: Honorable Shaykh, may Allah grant you success. I was in a state of wudu' (ablution), then I had a blood test done and blood was drawn. Does this invalidate the wudu'?
The Shaykh:
If the blood is a lot, it invalidates the wudu'. But if it is a little, it does not harm. Yes.
The questioner:
Then he says, may Allah preserve you: Does this affect the fast?
The Shaykh:
As we said, if it is a lot, it affects the fast. But if it is a little, just for the eye for analysis only, it does not harm. Yes.
