Najasah of the Bathroom
Question :

If the floor of a bathroom becomes najis and the essential najasah has been removed but the whole bathroom floor is wiped with the same mop that removed the najasah, does the whole area become najis? If one steps in it after some time, does his foot become najis when they are wet? If so, then does najasah transfer when my moist foot touches my room floor?

Answer :

Yes, the whole bathroom floor becomes najis in the said scenario with the existence of dampness, and whatever touches it with dampness becomes najis, provided that this was the only cleaning method used.
If the floor is cleaned through other ways as well in which the taharah of the floor is achieved, such as with running tap water, such that one is no longer certain of the najasah of the floor when it comes in contact with the foot or the clothes, then one can consider the foot as tahir.
This applies to any situation where najasah is doubted after being sure that taharah took place.

The Transfer of Najasah
Question :

I was using the toilet and the urine splashed onto my body which I did not wash. Also a few drop of urine fell on my underwear accidently, which I did not wash. I went to bed and started to sweat. Does that make the rest of my clothes Najis?

Answer :

The part of the body and clothing that came in contact with urine becomes najis, and whatever comes in contact with the najis body or clothing with transferring dampness also becomes najis. So, if the sweat transfers the wetness from the najis body or clothing to anything else, the latter also becomes najis.

Chain of Najis things
Question :

His Eminence has said whenever a najis thing comes in contact with something else with transferring dampness, it will be come najis too, no matter how many things may be in the chain of the transferring of najasah.
Would this not mean that everything around us is najis?

Answer :

This does not make everything najis, since one is not aware that they had been in contact with najis things with dampness, or one is sure that a particular thing became tahir and najis without knowing which one was first. In such cases it is considered to be tahir.

Najis Mobile
Question :

If my hand comes in contact with semen, and I touch a mobile phone, but I am not sure if I touched it with the najis hand or the tahir hand, then what should I do with this phone? I cannot wash it because it will be ruined. What do you suggest?

Answer :

As long as you are not sure that your hand was najis when you touched the mobile phone, you can consider it as tahir. Furthermore, najasah is transferred from one thing to another if the dampness in one of them is transferred to the other. If the mobile phone does become najis, then it cannot be purified again except with water. It is not prohibited to use it while it is najis.
