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.

Rennet
Question :

Some of the cheese products manufactured in non-Muslim countries contain rennet extracted from the calf or other animals.

It is allowed to use the rennet that is extracted from the animal that was not slaughtered according to Islamic laws, since it is tahir and exempted from the prohibition of using parts of the animal corpse.

Natural Leather
