Question :

If time is short and I know my clothing is najis, should I make the dress tahir and then make the prayer up afterwards or should I just ensure that I perform the prayers first so as to not make it qadha and then wash my clothes?

If the only clothing available is najis, offering the prayer in such clothing is valid in cases of cold weather or similar necessities. If it can be taken off, the prayer should be offered twice, once with it and once while naked, based on compulsory precaution.

Not all their food is najis. If their food is dry and they have not touched it with dampness, such as nuts or fruit, then they are not najis. You do not have to inform him of such a law. It is better to deal with him nicely and avoid dealing with such an issue.

People who do not Care About Najasah
Question :

If the items like knives, glasses or surfaces of kitchens and bathrooms become najis by people who do not care about taharah and they continue to make them najis again and again, then what should somebody do? Is it obligatory on him to avoid those areas? What if it is hard for our hands or clothes to remain tahir all the time?

Answer :

The validity of the prayer is conditioned with the taharah of the body and the clothes of the praying person and the place of resting the forehead during prostration. The rest of the place where the person is praying does not have to be tahir but you should make sure your body or clothes do not come in contact with dampness with the rest of the place of prayer if it was najis.
It is also prohibited to consume najis foods or drinks or what comes in contact with najis things with dampness.
You are not required to check for the state of najasah in things, but you can consider things to be tahir if you do not know that they came in contact with najasah. It is not a condition or a prohibition to avoid contacting najasah or najis things in other than the mentioned cases.
