impurity

Peshaab ke qatre kapre se dhona

Q: Me jab bhi Hindustaani baitul khala istimaal karta ho to istinjaa karte waqt baitul khala me girne wale paani ke chand qatray ur kar maqad ke dono taraf par jate he. Kya ye paani ke qatre najaasat-e-ghaleeza he ya najasat-e-khafeefa aur en ko dhona zarori he ya ne dhoye to shariat me maaf he. Har baar Istinja karte waqt mujhe baar baar baitul khala se paani ke qatre ur kar parne ka shak parta he. Jis ke wajah se aadha aadha ghanta istinja kartay huwe lag jata he. Baar baar en qatron ko dhota hoon phir paaki ka yaqeen nahi hota.

Walking with impure shoes on a carpet

Q: I stepped on some stool of an animal but was unaware until later in the day. The place I work is in a room that is carpeted. The day I was working, it was also raining making the soul of the shoe wet making me believe that the najasat has spread on the carpeted floor at my place of work. Now, as I work there on a regular basis I wanted to know:

1. If I would have to clean the carpet in the room?

2. How would I clean the carpet in the whole room as the carpet is stuck to the floor.

3. Would it suffice using a mop or wipes to just wipe over the carpet?

4. If I walked on the carpet again with wet shoes would the napaaki transfer from the carpet to my shoe to other areas e.g. car, home etc...

Doubts regarding impurity on the floor

Q: I had the urge to go to the restroom (for toilet). Before sitting on the toilet seat I usually check the toilet seat whether there is any thing on it or not (I bent my back while checking). The moment I stood straight, I was confused whether from the toilet or normal discharge that gushed out. It gushed so much (this time I really had the urge to go). It was watery and I am confused whether it was from the toilet or clear discharge and that I put my clothes on the floor. I am not sure whether the impurity touched  floor or not. Should I wash the floor? It happened to me nearly three times. 

Washing dishes with impurity on one's hand

Q: I had an impurity on my hand and it dried. I meant to wash it but I forgot and then I washed a pot (with my hand), heated up something in it and drank it. Is this pot (and what I drank) pure? I washed it under running water. Do I have to worry about the other dishes in the sink being impure since I washed the pot over these dishes (the water I was washing with ran all over them), or can I just assume they are pure?

Washing visible and non-visible impurities

Q: I had a question regarding the purity or purification of bed sheets or similar stuff impacted with semen (both visible stains as well as invisible). Please give a detailed and clear idea about the ruling regarding the same. If it is impure then how do I wash large bed sheets, mattresses or blankets in both cases having visible semen stains as well as non visible semen. If I sleep in the same setup do my cloths or body get impure?
