The ruling on the invalidation of wudu' by a small amount of blood and a large amount

Question:
If a wound occurs on the body and blood comes out of it and falls on the garment, does it invalidate the wudu'? And does one have to repeat the prayer in the garment that has been touched by blood? I ask for your guidance, may Allah love you.

Answer:
If the blood is a small amount, it does not invalidate the wudu', provided it comes from other than the two private parts. If blood comes from other than the two private parts and is a small amount, it does not invalidate the wudu', nor does it make the garment impure; a small amount of blood is excused. If it is from an animal that is pure in life, its small amount is excused; it does not invalidate the wudu', and it also does not make the garment impure because it is a small amount. However, if it is a large amount, it invalidates the wudu' and makes the garment impure if it is a large amount. This is determined by custom; what people consider to be a large amount is the standard.
