Q: What is the ruling on talking during the Adhan?
A: The Adhan and the Iqamah must be called in a relatively consecutive manner and therefore a little speech or even a little silence without need during it is disliked except for returning the greeting of salaam. Impermissible speech such as backbiting invalidates it. Source: Sharh al-Muntaha
