Blood of a Wound, Sore or Abscess on the Body or Clothing
Issue No.775- First: If there is blood of a wound, sore or abscess on the body or clothes of the prayer performer, and the condition is such that rinsing the body or clothes is hard, he may offer prayer with that blood so long as the wound or abscess does not heal up. And the same rule applies to the pus which has come out with blood, or a medicine applied to the wound that has become najis. However, if the wound heals up soon and the blood on the body or clothes can be washed off easily, then it should be washed and made ṭāhir.
