Question : I live in a high-rise building. A drop of semen fell on the floor in my apartment. It is not possible to wash the floor with running water, because it is not a bathroom, but it is a bedroom. I washed the semen using a mop, and then I washed the mop under running water and then washed the place again, and I did this several times. Has my floor become tahir? Or is my mop becoming najis every time?
Answer : The taharah is not established by this; when you wipe the najis part of your floor with the mop, it becomes najis every time you do that, and the najasah is spread to surrounding areas.
One should pour the water on the najis part of the floor, and collect the water with a cloth, and the place will become tahir.
Question : I have read that for making the hand tahir by qaleel water, it is necessary to pour the water on the hand, and when the water flows off the hand the hand will become tahir. Does this apply to all body parts as well as the penis? What if the najasah is urine?
Answer : Yes, the separation of water from the najis object is a condition in the process of purification if the water used is little (qaleel). This ruling is the same for all parts of the body, including the penis.
If the najasah is urine then one needs to purify the najis object twice when little water is used.
Question : If one gets a Najas thing in his mouth, such as pork, how does he purify his mouth? Is it enough to spit it out, or must one wash his mouth once with running water, thrice with little water, etc?

Question : I was told that one must remove the najis part from an impure object in order to make it tahir again. Is this true?

Question : How would I purify an electronic device which has become Najis, while the water might damage the device?

does not become Najis when it touches it.

Question : How many days are required for istibra of animals that eats filth (najasah)?
Answer : The istibra of the animal that eats human excrement is by preventing the animal from consuming human excrement for a number of days, in such a way it is considered as not consuming human excrement, and the period depends on the type of animal.
The sharia defines this period for the camel to be forty days, for the cows to be twenty days (and better that it is thirty days), for the sheep to be ten days (and based on a recommended precaution it is fourteen days and as an obligatory precaution this applies to the goat too), for the duck it is five days (and it is better that it is seven days), and for the chicken it is three days.
For other animals, as an obligatory precaution one should do the istibra of the animal based on the longest period after which the animal would conventionally not be regarded as one that consumes human excrement, and also considering the size of the animal and comparing it to the mentioned list.

Question : How do I purify myself if I touch real leather of an animal that has not been slaughtered in accordance to Islamic religion? I would normally remove the Najasah, then pour water over it a certain number of times, but in this case is there anything to remove?
Answer : If your hand comes in contact with the impure leather with dampness then it became impure even without the actual Najasah being transferred to the hand. The hand can be purified then by washing it once with water.
If the contact took place without transferred dampness from one side to the other, then this does not make the hand Najis.
