Answered by Shaykh Yusuf Weltch
I’m a chronic sufferer of waswasa. I suffer from various skin problems like acne and eczema. Sometimes a wound dries, and I go to shower or wudu. Afterward, I found that it had leaked small pus or liquid and could not tell if it had spread to wherever the water from the shower or wudhu spread or not if my clothes or any other body part/floor that touched the water from wudhu/shower najis?
Washing a body part with a small drop of pus that didn’t flow, if water flows over it (like droplets after shower) and spreads, does this water make everything in its way, najis?
Is using the tissue to clean the public toilet bowl enough to make it pure? If I sweat, won’t the najasa (if there is any) come back?
In the Name of Allah, the Most Merciful and Compassionate
Small Amount of Pus
For blood or pus to invalidate the wudu when exiting the body, it must exit with such strength that causes it or would cause it to flow. [Tahtawi/Shurunbulali, Hashiyat Maraqi al-Falah]
If one is unsure whether it flowed, especially one who suffers from misgivings (waswasa), the assumption is that it did not flow. Any doubts to the contrary are ignored until and unless one is reasonably sure otherwise. The reasonable surety is based on proof. [Ibid.]
Non-Flowing Pus is Pure
In addition to a small amount of pus not invalidating the wudu, it is also not considered impure. Even though a minority opinion states that non-flowing blood (or pus) that contacts a liquid makes the liquid impure – this cautious opinion is not taken by one who suffers from misgivings (waswasa) as a principle. [Ibn ‘Abidin, Radd al-Muhtar]
Thus, the majority opinion that non-flowing blood (or pus) is pure is to be taken in your case. If water comes in contact with it and moves to other places, the places and the water are all pure. [Tahtawi/Shurunbulali, Hashiyat Maraqi al-Falah]
Wiping the Public Toilet Seat
Whether public or private, the toilet seat is made out of a non-porous material (often porcelain). Non-porous materials can be purified by wiping them such that no traces of impurity are visible. This is obviously in the presence of impurity. If no impurity is visible, the seat is pure, and any doubts to the contrary require proof to affirm. [Ibid.]
