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?

Q:

1. I just want to ask in the zuhr and asr salaah when you are behind the Imam are you going to recite the surah fatiha and then after fatiha do I need to recite another surah? Or only the surah fatiha?

fatiha silently while the imam is reciting another surah? I follow Abu Hanifa.
