The ruling on praying in a garment with a small spot of blood on it

Question:
This questioner says: What is the ruling on one who prays in a garment that has a small spot of blood on it?

Answer:
Blood must be washed. This blood, if it is impure—if it is blood from permissible meat, meat that contains blood and it ends up on the garment—there is no harm in it; leniency is allowed in this case because it is permissible to eat the meat with the blood in it. This is permitted. However, if it is human blood, or the blood of an animal that is not eaten, or what comes out of the slaughtered animal at the time of slaughter—the flowing blood that spurts from the jugular veins—this is impure. If it affects the garment, it must be washed. When a woman asked the Prophet (peace and blessings be upon him) about menstrual blood that affects the garment, he said: scrape it off, then meaning wash the blood. So blood is impure and must be washed. If a person prays in it while forgetting and not knowing about it, his prayer is valid. But if he did it intentionally, his prayer is not valid because he prayed with impurity while not being forgetful; he was intentional, so his prayer is invalid. But if he was forgetful or ignorant, his prayer is valid. Yes.
