Q: I have a graze on my front private part, a bit of skin came off. There is now a build up of waterpus there. The waterpus stayed within the wound and I prayed Asr and Maghrib with the same wudu. I prayed Esha late and when I checked the wound I noticed the water/pus had flowed beyond the wound. I can’t be sure if it soaked through my underwear and onto my trousers. I just changed my underwear but wore same trousers to pray. I can’t be fully sure it soaked through. I just changed them due to precaution. I have these doubts always.
A: From the time you are sure that the pus had flowed you will repeat your namaaz.
And Allah Ta’ala (الله تعالى) knows best.
