Question: I know impurity less than 5cm is excusable, according to the Hanafi Madhab. I release an excusable amount of madhi. Do I still have to do wudu?
Answer: In the name of Allah, Most Compassionate, Most Merciful,
Assalam’aleykum, I pray this finds you in the best of states.
Jazakum Allah khayr for your question!
Yes, you still have to perform wudu in the situation you have described because filth has exited your body. [ Nur al-Idah]
What is excused is to pray with your unwashed body or clothes when it has been affected by the excusable amount of filth. [ Nur al-Idah]
Nonetheless, it is far superior to wash even an excused amount of filth before praying as it is disliked to pray in such a state. [Nur al-Idah]
And Allah knows best.
May Allah Most High grant you the best of this world and the next. Please keep us in your du’as!
