Inaudible Dua after Salaah

Q: I would like to know the ruling concerning dua after the congregation in the masjid. Should it be done audibly or should it be done inaudibly. Some people take offence at the fact that in certain masjids the day after congregation is made inaudible and they feel that because it is a congregation we should make the dua are similarly for everybody in an audible voice.

Suspending a talaaq

Q: My sister and brother in laws abuse me very badly so I told my husband that I won't cook food for them. Then my husband said that if you won't cook food for them then I have also one condition that you have to leave your mother forever and never talk to her otherwise our relationship is over. On this condition I decided to go to my parents home then my husband stopped me by saying that do whatever you want but don't go. Then we started living as husband and wife but again he started forcing me to cook food for them and the argument continued but one night on 6 October 2016, I told my husband that why are you always forcing me to cook food for them as I have told you that I won't cook. Than my husband said that I have also told you that leave your mother otherwise our relationship is over talaak. Since then I am living with my parents. My husband says that come back I have not given you a talaak. Please tell me whether I am divorced or not?

Qadha namaaz

Q: If anyone starts to offer 5 times namaz at any time of his life, so is it mandatory for him to offer all the due salats (Qaza-e-umri) first, which he has not been prayed since he was 12 years old?

Uttering statements that lead to kufr

Q: Recently I have heard one scholars speech regarding kalima e kufr (saying bad words about Islam even in a joking way) can cause an individual to become a kafir and his nikah will break.

Actually my wife used to make comments about my beard some times that she doesnt like it and it doesnt suit me. The scholar said that saying this will make her a kafir (in the video).

Please suggest whether my nikah is valid and if not then how do I renew my nikah.
