Imaam performing two jumuahs in one musjid

Q: In our Masajids there are two Friday Prayers are being held. And one Iman leads the both Salah in terms of delivering the Khutabas and as well leading the salah. As we understand Juma is only Fard once not twice. Could you please help us to understand whether this is allowed or not, and give us some detail explanations in terms of it's validity. We would like to share your explanations with the local scholars. 

Using kinaya words of talaaq without the intention of talaaq

Q: My marriage is in 10th year. During the first two three years of my marriage, when me and my wife have a heated arguement, in the rage of anger, I asked her to go to her father's house, so that I can get some space to cool my anger. I used different kind of words as "I don't want to see your face", "Go away", "I will not show my face again" and many more words that I don't remember. I don't know how much time this happened, but it happened at least 10 times or more.

Now I came to know about Talaq with kinaya words, I am worried that if my marriage is valid or not. Your answer says that if those words are used in your area. I want to tell you that in my area, only the word "talaq" is used to give talaq.

Also I want to state that my intention was to find some lonely space when I uttered these words. But I doubt that in rage of anger, it is quite possible that I have feelings to get rid of my wife forever.

So, my question is that if a husband does not remembers that if has pronounced kinaya words, will be benefit of doubt will be given to the husband or not? Or, for the sake of "ahtiyat" and "taqwa", should I separate from my wife as I am fearing that if "zina" is taking place between us.

Qasr salaah

Q: I am staying in a different city as I am working there but I want to know whether I will offer qasr salah if I go to below cities for less than 15 days

1. City A where I was born and don't reside now but I have a home which I gave to rent

2. City B, I have flat there but I don't reside and go once in a month

3.City C, my in laws home.

What should my wife offer here Qasr or full?

Also during Haj we stayed in Makkah for 14 days and on 15th day we left to Mina before Fajr. I offered Qasr Salah but when I came back few mufti's told you were muqeem. I told them once you reach destination from that time you should calculate 15 days. But they mentioned we need to calculate from our home and also even if we stay for one hour of a day we should count it as one full day. Is this correct? But I told them how you can assume one hour as one full day. Is my understanding correct?
