Swallowing Blood in One’s Mouth: Does it Invalidate My Fast?

Hanafi Fiqh

Answered by Sidi Waseem Hussain

Question: I just have a question regards to blood in the mouth. Does it invalidate the fast to swallow blood in the mouth?

Answer: Walaikum Salam Warahmatullah,

Bleeding in the mouth will only invalidate the fast if one swallows saliva when the majority of the saliva is reddish.

One is not required to check the saliva to see whether it is red or not, and there is no reason to assume blood has been swallowed unless one is certain that it happened.
