The ruling on the prayer of one who has a small amount of blood on his garment

Question:
What is the ruling on the prayer of one who has a small amount of blood on his garment? Does the prayer become invalid if he is aware of it?

Answer:
A small amount of blood is excused; a small amount of blood is excused. However, if it is considered a large amount by custom, it is not excused. So, if he prays while knowing that there is a large amount of blood on his garment or his body, his prayer is not valid.
As for a small amount of blood, it is excused. Likewise, if it is a large amount but he forgot it, or was unaware of it, and he prayed, and he did not know until after the prayer, his prayer is valid. The same applies if it is another type of impurity, such as urine or something else, on his garment or on part of his body, and he forgot it until he prayed; his prayer is valid. Yes.
