Question
Is Blood or Pus from a Large Pimple Naajis and Does It Break Wudu? The leakage of pus was continuous. Pus was also yellowish greenish. And sometimes mixed with blood.
Answer
In the Name of Allah, the Most Merciful and Compassionate
If the blood or pus that came out from the pimple was such that it flowed to another part of the body, the wudu is broken and the blood/pus is impure. If however, it was little and did not flow, rather it just remained in the place from which it came, the wudu is not broken and the blood/pus are not impure. [Shurunbulali, Maraqi al-Falah]
The color of the blood or pus does not affect the ruling.
Hope this helps
Allah A’lam
