Calculating zakaat

Q: I have a question on zakat.

I was supposed to give my zakat this year Ramadan 2020 But till August I have not paid my zakat on gold jewellery of my wife, as I am paying on her behalf. The other zakat on my bank balace I have paid.

Now my questions are:

1. The value of gold in April 2020 in Ramadan in which I calculated my zakat every year was farz, and at that time the value of gold in India was less and not due to lock down or other reason the value of gold has shot up very high. So will I weigh the gold jewellery and pay zakat on the total value of gold 2.5% in the new rate of gold which is in August 2020 or will I have to pay zakat 2.5% on the rate of gold which was in April 2020 in Ramadan this year.

2. Will my wife be liable to pay zakat or I can pay on her behalf from my bank balace?

3. I had some gold jewelley which I purchased few years back and I purchased some jewellery in August 2020 when I married. Now my zakat date every lunar year is on 27 Ramadan. So this year 2020 Ramadan was in April-May 2020. So the jewellery which I purchased in August 2019 last year has not completed 1 (one) complete lunar year so will I calculate my zakat on the particular jewelley or will I calculate after August 2020 as it will complete full one lunar year. But my zakat date is in Ramadan, either I have to take out the zakat on full jewellwey this year 2020. Or I have to pay my the zakat on the particular jewellery which I purchased in 2019 the following year i.e. 2021 in Ramadan. But then it will be over one year for this particular jewelley which I purchased in August 2019. What should I do?

4. Some gold jewelley is of 21 carat and some are of 24 carat so will I have to pay zakat on their differnt value or I have to just weigh it all as one and pay the zakat 2.5% on the total gold jewellery?

5. How would I know that zakat has become farz or wajib upon me? How much money in Rupees do I have to have so that I become saahib e nisaab. Whether it is 20,000/- or 50,000/- or what amount? What is the mark? I am asking the nisab in relation to indian money in Rupees. Not the value of gold or silver as I heard that if one has 612.36 gm of silver or 87.48 gm of gold one is called saahib e nisaab. Suppose I have cash in bank Rs 30,000/- (thirty thousand) - indian money and I have gold jewelley a small ring, a nose pin small, and a silver anklet so now how do I know that I am a saahib e nisaab. As I do not have 612.gm of silver nor do I have 87.48 gm of gold. How do I calculate zakat on this. It is very confusing. 

Calling Shias kaafirs

Q: I belong to a community who believes that majority of Shia are kaafir and want me to call them kaafir too. When I say that I leave this to Allah to decide as I am no one to judge then they call my aqeedah distorted and some even go further by saying that I am an Athiest.

Is it mandatory to call others kaafirs or what does Islam say for people who don’t want to give their verdict?

Asking a kaafir to make dua

Q: Can a person ask a kaafir to make dua without any belief that their idols would fulfil their wish. He believes that only Allah Ta'ala can fulfil the wish of the kaafir and that there is no other God that exists except Allah, but just saying "dua karna-pray for me/us" to a kaafir, would this constitute kufr which takes a person out of the fold of Islam? 

Woman wearing short or tight clothing at home

Q: Sometimes I wear slightly short or tight clothing at home, e.g.: 3/4 pants or a t-shirt who's length isn't completely over my buttocks. However my aw0ah is always covered. I don't even wear sleeveless. However, my father says that this is wrong and disrespectful because we live with my brother and grandfather. He always makes me change. Please advise if this is wrong or disrespectful and if I'm allowed to dress like this in my own home. Outside I wear hijab

Hurmat-e-musaaharah

Q: I have some questions about hurmat musaharah.

1. Is it established between a mother and daughter?

2. Is it established if one has wet dreams about incest or a sexual dream that has mahrams?

3. Is hurmat cancelled if parents remarry and sincere repentance is made? 

4. Lust is a strong sexual desire. If I don't feel a strong desire but I feel some type of lustful feeling that I try my best to control inside my heart at the time of touching, is this hurmat musaharah?
