Salaah

Q: I have a situation where in my work place in Saudi Arabia (far from any musjid in construction site), the person that often is imaam of the small musallah we perform zohr and asr salah, makes masah over his normal cotton socks when he makes wudu. 

I read salah for few months behind him and only found out about this recently. 

He confirmed that some scholars in Saudi passed a fatwa that its permissible. It would seem that many of the general public here follow this fatwa. 

I do not want to argue and create fitnah based on the situation. I know the fatwa is that wudu is not valid if masah is made over normal cotton socks based on majority opinion. 

However, based on my situation/ the fact that I did not know or could not control the imaam, is my previous salah valid or should I repeat it? 

Also, going forward, what should I do: Can I read salah behind him, based on the fact that I cannot control the imaam - perhaps consider him a different madhhab/ different opinion with salah being valid Insha Allah or is salah invalid for sure in which case. Should I read salah behind him and repeat it or should I try to avoid and read on my own. This will result in me not being able to make salah in jamaat at work and possibly create division. (Also reading salah and repeating is a challenge especially asr based on limited time and people observing you).

Q: If a person misses a rakaah of his Salaah with jamaat and he is a masbooq then what is the correct method of standing up? 

I have noticed that everyone stands up after the first salaam. Is this correct or is it better to stand up after both the salaams?

Q: Is it permissible to picture that one is standing in front of the Roza-Mubarak when reciting Durood Shareef in Salaah?

Q: Is it correct to say or is there any Hadith that says that a woman's musalla is like a masjid and before starting a salah or standing on the musalla in the house she should read: Allahumma Aftahli Ab Wa Ba Rahmatik" like how men do before entering masjid. 

Q: Given the spread and propagation of Interfaith and the Abrahamic Religion, what is the shar'i ruling on performing Salaah in a multi-faith prayer room? 

Multi-faith prayer rooms are now found at airports, petrol stations, malls, offices etc. Some multi-faith prayer rooms have the symbols for each religion, at together, displayed on the wall or door.

Q: If I am performing salaah as a Hanafi behind a Shaafi and he makes an error by forgetting the first tashahud in Asr Salaah, what is the right way of making sajdah sahw or should the salaah be repeated?

Q: A man passed away, leaving behind his wife, a son, two daughters, a brother and a sister. 

Let's say he left an estate valued at $100,000. He had verbally expressed his wish to give one-third of the estate to charity, but there is no written will. 

How should his estate be calculated and distributed according to Islamic inheritance laws? 

Additionally, because the deceased was ill for the last six months and suffered from dementia, he was unable to perform Salah (prayers) during that time. Should Fidyah be paid for the missed prayers, and if so, from which portion of the estate?

Q: Alhamdullah, I am pregnant. So can I offer nafal and sunnah Salah on the chair and perform the fardh Salah by standing.

Q: I'd like to know if there is any ruling with regards to a person that has passed the age of 80 and they do not perform salaah.
