The Evidence for the Impurity of Blood and the Ruling on Spilled Blood

Question:
The Shaykh said: What is the evidence regarding the impurity of blood? He exited from the two prostrations, and if he had sworn an oath or something else, he would be carried to Paradise, and then he would not be asked about the prayer, nor would it be washed off him.

Answer:
Blood is ritually impure. This is established by the saying of Allah the Exalted: They say that the "flowing blood" is that which has been drained from its place; this is what they consider to be the flowing blood. As for those who say it is pure, they cite what the questioner mentioned regarding Ibn 'Umar and others having blood and filth on them. Furthermore, the correct view is that the flowing blood is the blood that comes out of the two main veins at the time of slaughter. This is the flowing blood, not blood in general. It is specifically the blood that comes out of the two main veins during the ritual slaughter, which spurts out and flows with force. This is the flowing blood. Yes.
