Distance between the Imaam and Muqtadis

Q: Will men get the same reward as performing salaah in the Haram if they perform salaah in the hotel jamat khana following the imam through the speaker?

Q: I've had a tibial plateau fracture and I have not been able to walk. I have a masjid right beside my house. My question is - can I perform the salaah in my house while following the masjid jamaat, since I can clearly hear the imaam from my house?

Q: My home is very near to the masjid and the voice of the imam can be clearly heard in my room through the loud speaker of the masjid.

Can I join the prayer from my room as the imams congregation and qirat can be heard from my home? Due to the pandemic of corona the government has ask us to stay at home.

Q: During a special time like an epidemic, is it permissible to pray in congregation by following an imam over Skype? For example in Jumu'ah, if the imam delivers the sermon in Skype and leads the prayer, can the muqtadi take part in the congregation from their houses (which is different than the imam's)? Is this congregational prayer valid? If not, what is the basis of this invalidity according to Quran and Hadith?

Q: My home is near the musjid, and the voice of the imaam can clearly be heard in my room through the loud speaker of the musjid. Can I join the salaah of the musjid and follow the imaam from my room, as the imaam’s qiraat can be heard from my home?

Q: I read the Q&A related to performing jamaat salaah in a hotel in Al Haram, at http://muftionline.co.za/node/13093 and http://muftionline.co.za/node/25791 and http://muftionline.co.za/node/27480

In Pakistan, many masjids have 1st floor and few have 2nd floors as well. Please enlighten me that performing jamaat salaah on 1st and 2nd floor is valid or not?

Q: For the saffs of the men, we understand that there should be continuity, and a gap larger than 2 saffs between saffs will cause the link to be broken, thus the salaah of those behind the gap will not be valid. (In the situation where there isn't any river, etc. inbetween).

What is the ruling regarding saff continuity for ladies? If a masjid has a room at the back, but between the last saff of the men and the women's room is a large gap, would the ladies salaah be permissible behind the imam? (assuming all other conditions are fulfilled such as the imam making niyyat for leading the ladies).

Q: In the Holy Mosques of Makkah and Madinah, outside the mosques, there are big verandas (open space). It is seen that the people walk in these verandas with their footwear on.

1. Can we pray on the floor without a prayer mat?

2. Will our salah be valid? 

Q: Nowadays, some people are performing salaah in the hotel near the Musjid al Haraam while following the jamaat of Musjid al Haraam. The hotel has speakers installed and the recitation of the Imaam of Musjid al Haraam can easily be heard. However, since the Imaam is not present infront of the muqtadis, I am doubting whether the salaah is valid or not. Is it permissible for people to follow the Imaam in salaah while in their hotel rooms? Similarly, is it permissible to follow the Imaam in the hotel jamaat khaana? 

Q: Can one follow the jamaat salaah of the Haram from the musalla in the hotel/hotel room?
