Impurities on the body

Washing clothes in the washing machine

Q: Please can you advise if a bed sheet with stains (possibly not najis, possibly sweat or drooling saliva) has been washed in the washing machine with other stuff but the stain has not been removed fully then is the sheet as well as other stuff rendered impure even after 5 rinses and spins or is it paak. Also is raw fleshy skin due to a burn peeling off on the arm considered pure?

Is sweat napaak?

Q: I read somewhere that if one had masturbated, their sweat is napaak. If someone touched their phone and their hand started to sweat, is it napaak if they had masturbated? What would be the correct way to make it paak?

Mazi

Q: Some sexual thoughts came to mind while sitting on the sofa, so I started thinking about it for some time. After that I found thin liquid automatically came out from penis (it also got erected). Does this make ghusl compulsory for me? If such things happen 3-4 times a day, should I do ghusal every time?

Finding impurity on one's body after istinja

Q: Please can you help me with the following?

1. Yesterday after passing stool I showered and cleaned myself to the best of my ability. Later that day when I cleaned myself in the toilet I found my private parts were still a bit dirty. I am now concerned that due to the fact that I showered and dried myself i could have spread the najaasat all over my body and therefore wherever i sat during the day and possibly perspired could have become napaak. Please let me know if this is in fact the case and whether I have to go back and wash all the areas i sat on during the day, including my towel shoes etc

2. Sometimes after cleaning I notice a dead insect on the cloth that I have cleaned my house with, would this then make all the items I wiped with that cloth napaak and is it necessary for me to wash these items three times?

3. We were out at a restaurant with family and friends and when we got home I realised that my daughter had urinated in her pants. I then began to get concerned that she was sitting on the chairs in the restaurant and touching everything there including the food, utensils etc. Furthermore she also sat on our family and friends laps and touched their belongings. I am not sure how wet her clothes were at the time and whether the urine has made all these things napaak. Please can you advise me as to what to do in this situation.
