Does blood coming from the gums invalidate the fast?

Question : Okay, this questioner says: When I rinse my mouth for wudu, especially during the month of fasting, blood comes out of my mouth without my intention. Does this invalidate my fast?

Answer : It does not invalidate the fast if blood comes from the gums during tooth cleaning with the miswak or during rubbing the teeth with the finger. Likewise, the fast is not invalidated by blood coming from a wound, or from a nosebleed, or something similar, because the fast is not invalidated except by cupping or what is equivalent to it, such that a large amount of blood is drawn from the person, leading to weakness of his body. But we return to the blood that comes from the teeth of the fasting person. We tell him: If blood comes out, do not swallow it, because blood is not saliva. It is something extra beyond saliva, so it is not permissible for the fasting person to swallow it. If he swallows it while knowing that it is blood.
