If there remains a trace of blood in one's mouth, does this invalidate one's Sawm?

Q: My mouth bleeds during Sawm (Fast), especially after waking up. At time of Madmadah (rinsing the mouth) during Salah (Prayer) times, the color of the blood becomes light red, and sometimes turns yellow on rinsing twice or thrice. How can I swallow my saliva, taking into account that bleeding may continue for a while? What is the ruling on swallowing the yellowish liquid that does not taste as blood? (Part No. 9; Page No. 211) I consulted a doctor who prescribed medication for me but it was in vain.

A: If the case is as you have mentioned, do your best to get rid of the blood in the saliva through Madmadah. Additionally, be careful not to swallow this blood or the slight yellowish liquid in your saliva, Therefore, there is nothing wrong in that and your Sawm is valid In sha’a-Allah (if Allah wills).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
