Will talaaq take place if the husband tells the wife "Jao tumhain chor dia"

Q: Me and my wife often have verbal fights. One day after a verbal fight she asked me to leave her and said, "Mujhay chor kyun nahi daytay" In extreme anger I replied ,"Jao tumhain chor dia" and repeated thrice but I didnt intend divorce nor I know that these words may intend for divorce so we ignored and spent normal married relation. After months of this incident, one day my wife started having doubts that perhaps the words I used are intended for divorce. Now we both are so worried and dont know whether we are divorced or not. Please guide us.

Replying to the Azaan of different Musjids

Q: I live in a Muslim Village of about 200 households. We have 6 (six) mosques in our locality and all of them uses loudspeakers for Azan. I’ve read that we must answer the call to prayer. Sometimes the Azans from all the mosques don’t overlap and I’ve been left wondering if answering one is enough or do I have to answer all of them. Please clarify. Also on one site I read that using loudspeakers for Azan is an act of Bida’at. Is it so?

Inheritance

Q: My father owed my grandfather R40 000. Its been few years since my grandfather passed away. My father is now able to pay of the debts which will go to the heirs (none of whom have passed away) as inheritance, who are: my grandmother, my father's 3 sisters and my father himself. I would like this R40000 to be divided amongst the heirs when my father wishes to pay back the debt?
