Question: What is the ruling of the one who bleeds whilst fasting?
Response: If the person was to bleed without intention whilst fasting, then his fast is valid.
And with Allaah lies all the success, and may Allaah send prayers and salutations upon our Prophet Muhammad (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
