Imam Bukhari narrates: Ayyash bin al-Walid narrated to us, he said: Abdul A'la narrated to us, he said: Humaid narrated to us, he said:
I asked Thabit al-Bunani about a person who speaks after the Iqamah for prayer. So he narrated this hadeeth to me from Anas bin Malik, may Allāh be pleased with him, that the Iqamah for prayer was said, then a man came before the Prophet ﷺ, and he held him back (in conversation) after the Iqamah for prayer.
