Uncertainty Regarding Swallowing Blood Whilst Fasting
Q: I have a disease of bleeding gums and there will be little blood in my mouth. I can’t keep on spitting whilst I am in the office and after I get up from sleep. When I spit there will be some blood on it, so I don’t know whether I had swallowed it or not. If it is swallowed while sleeping, will my fast be invalid? Are there any excuses?
