Q: I have read that in order for najasat to transfer from one place to another, flowing wetness needs to be transferred. Now if my hands are not paak but dry, and I hold a cloth in my hand, does it become napaak?? The point where I am confused is that a hand is always sweating and in bright light very tiny droplets of sweat are always visible. Now if in such a scenario, if I touch a cloth, given my hands are not paak but apparently dry and I cannot see any wetness transferred to the cloth, does the cloth remain paak? Does this situation correlate with the ruling that a najsat with size less than a dirham coin could be ignored?

Q: I had released semen at night which had dried on my private area when I woke up in morning. When I did ghusl, the dried semen was not coming out, even after scratching or rubbing the skin. I left it and completed my ghusl, and offered fajr. This dried semen did not come out until I scratched it again after a week, and even then I think it did not come out completely.

1. Does this dried semen keep me impure?

2. Will I have to repeat the prayers I offered with this?

Q: If a little kid urinates in a bucket, how to get rid of impurity from the bucket?

Q: I had a metal filling put in whilst in a state of janaba and I am now concerned whether my ghusl will be valid once performed? As the metal fillings have covered my teeth while I was junub.

Q: If whilst brushing the teeth, some blood is seen in the saliva, does this break the wudhu?

Q: How many days my body will be "napak" if I smoke cigarettes?

Q: If a person made ghusal and thereafter notices a small bit of nail polish on their nails, will they have to repeat the entire ghusal?

Q: In a case where one was not aware that the earrings have to be removed for ghusal (so that water reaches that area), what should she now do about her past salaah etc?

Q: My maid mopped over my baby urine by mistake and she continued to mop with the same water in other rooms too. Now what should I do? Shall I mop 2 times again?

Q: In my office washroom, the janitors keep the floor dry using a mop. Now the toilets are separate from the area where there are wash basins. However, the janitors use the same mop to clean the floor of the entire washroom (toilet and the washbasin area). Now when washing myself or performing wudoo at the wash basins, drops of water usually fall down on the floor. Does these drops become napaak after splashing from the floor? In the start I tried to avoid these drops from falling and then bouncing on my feet and clothes, but it is almost impossible and every now and then I get water splashed on my feet and clothes. What I should do in such a case? If I become napaak, how can I perform salah then because I have no way to change my clothes in the office and it happens too frequently?
