Following the imaam in salaah over Skype

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?

Husband making wife pay for household expenses

Q: I want to know if a woman should be doing all the payments for a man while he sends all his money to his family. I know women must assist but not pay for everything while the husband is saving his money for his family. My husband is religious; he reads namaaz 5 x a day. I love him very much. Because I don't have children he takes me for granted to be a slave and support him. Please tell me how how should I approach him without us having a problem. He always tells me that Allah subhanallah is happy with him and no matter how much wrong he do does, his 5 x a day namaaz will get his sins washed away. I don't want to break my marriage.

Gargling while fasting

Q: I have an asthma problem, due to which I am unable to hold my breath as long as a normal person does. Due to this, my main concern is with regards to gargling and rinsing of the nostrils in ghusul and wudhu. What should I do when I am fasting? Because, at times, when I gargle, I feel the water going down my throat (because of the shortness of my breath), despite me trying to keep the water at the front of my mouth.
