Masturbating in a dream

Q: I saw in my dream that I was masturbating .But I doubt that any vaginal fluid came out or not. Can I perform namaaz and read quran. And once in the month of ramadhaan I saw that I was masturbating then my roza will be valid or not?

Husband suspending three talaaqs upon the wife carrying out a certain action

Q: My husband told me if I will call or contact a friend of mine, I will automatically get three talaaqs. I wanted to know if this is true according to Shariah? Will I really get divorced if I call that friend? And if this is true then how can I talk to that friend if I have a serious issue to discuss with her without getting divorced? Please help. I hope i will get an answer soon.

Reciting behind the Imaam

Q: I require clarification on the following

1.During Dhuhr and Asr, when we say our Salaah in silence, must the Imam and the Musallis recite the Surah/Ayats in silence, each on their own or must the Imam alone recite the Surah/Ayats and the Musallis must keep quiet?

2.On Jumu’ah Day why is the Adhaan said twice instead of one as in the other days of the week?

Invalid will

Q: If a husband and wife make a will before hand stating if either one of them dies, the property which they live in will transfer to the wife or husband whoever is alive. I just want to clarify if the last person died, than how would you suggest the proper way to distribute the property as we don't have no child. JazakAllah for your valuable time. If you can kindly give e.g. in detail.
