Does donating blood invalidate the ablution?

Question:
Honorable Shaykh, the questioner asks: Does donating blood invalidate the ablution?

Answer:
This is another issue. Blood is ritually impure; blood is ritually impure. As for whether it invalidates the ablution, if it comes out from the two passages, it invalidates the ablution as mentioned previously. But if it comes out from the rest of the body, this is a matter of disagreement among scholars with two opinions. The stronger opinion, and Allah knows best, is that it does not invalidate the ablution. The stronger opinion, and Allah knows best, is that it does not invalidate the ablution, because the Companions used to be wounded in battles, with blood flowing from them, and they would pray while the blood was on them. And 'Umar (may Allah be pleased with him), when he was stabbed while praying and blood flowed from him, he completed his prayer; he completed his prayer. This indicates that blood coming out from other than the two passages does not invalidate the ablution. Yes.
