Asking the husband for divorce

Q: I am married. I am not in love with my husband. I dont wish to be with him anymore. I dont want to hurt him but I want to leave him. He has noticed changes in my behaviour and I did mention that I dont want to be with him. He threatens me and I feel forced to be with him. What is the easiest way forward for me?

Bridegroom mumbling some words in Arabic at the time of nikaah

Q: Was this nikah valid?

The Imam told the bridegroom clearly to many witnesses in the masjid that ‘do you accept so and so’ upon which the bridegroom mumbled a few words in Arabic (as the bridegroom was a Talib Ilm so probably wanted to say the Arabic phrase). The mumbling could be heard by the audience.

Does it matter if the audience didn’t understand what was being said by the bridegroom?
