Is blood ritually impure? And what are its categories?

The questioner : The questioner asks: Is blood ritually impure or not? Please explain in detail.

The Shaykh : He. This is an exam question. Regarding blood, if we want to explain it in detail, as our brother the questioner requested, we say: Blood that comes out of an impure animal is impure, whether a little or a lot. For example,
Blood that comes out of a pig, for instance, or a dog is impure, whether a little or a lot, without distinction, whether it came out while the animal was alive or dead. Second, blood that comes out of a pure animal while it is alive is impure after death. Pay attention: blood that comes out of a pure animal while it is alive is impure after death. So, if it is in a state of life, it is impure, but a small amount is excused. It is impure, but a small amount is excused. Like what? A pure animal in life is impure after death. A camel. Right? A camel. Well, sheep are pure in life and impure after death. The evidence for their impurity after death is the saying of Allah the Exalted: We say this is impure, but a small amount is excused. This comes next.
The third is blood that comes out of a pure animal in life and after death. What is its ruling? Blood that comes out of a pure animal in life and after death is pure. It is pure, and it does not have to be washed, except that most scholars exclude human blood from this. Human blood is blood that comes out of a pure animal in life and after death, and yet, according to the majority of scholars, it is impure, but a small amount is excused. Well, how many are these? Ha, four. How many? How many? How many categories did I mention? Three. Well, who can repeat them? Yes, please. Pure in life and after death. What is the ruling on this blood?
This is pure, both a lot and a little. It is excluded from this, ha? Human blood. It is impure according to most scholars, but a small amount is excused. Well, this is one. It is not like that. "Like that" means we did not categorize it. The second category, yes. It becomes impure. No, it is impure, a little and a lot, but a small amount is excused. Well, the third? Yes. A lot and a little, and it is not excused. Well, well done. Hurry up.
The fourth is blood that comes out of the passage, from the human passage, meaning it came out from the anus or the penis. This is impure, and a small amount is not excused. Because when the women asked the Prophet (peace and blessings be upon him) about menstrual blood that falls on the garment, he ordered it to be washed without distinction. So, these are four categories of blood. Well, do we accept his question without a paper, everyone? What is this? Is this a new follow-up? Well, for the benefit, do we accept it?
Well, we say that blood that comes out of a human being from other than the two passages does not break the wudu, whether a little or a lot, such as nosebleed blood and wound blood. Rather, we say that anything that comes out of the human body from other than the two passages does not break the wudu, such as vomit, blood, wound fluid, and others. Yes.
