Humaid reported : I asked Thabit al-Bunani whether it was permissible for a man to talk after the qamah had been pronounced. He narrated a tradition on the authority of Anas: (once) the Iqamah was pronounced, and a person came to the apostle of Allah (ﷺ) and detained him after the Iqamah had been pronounced.
