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.
حَدَّثَنَا عَيَّاشُ بْنُ الْوَلِيدِ، قَالَ حَدَّثَنَا عَبْدُ الأَعْلَى، قَالَ حَدَّثَنَا حُمَيْدٌ، قَالَ سَأَلْتُ ثَابِتًا الْبُنَانِيَّ عَنِ الرَّجُلِ، يَتَكَلَّمُ بَعْدَ مَا تُقَامُ الصَّلاَةُ فَحَدَّثَنِي عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ أُقِيمَتِ الصَّلاَةُ فَعَرَضَ لِلنَّبِيِّ صلى الله عليه وسلم رَجُلٌ فَحَبَسَهُ بَعْدَ مَا أُقِيمَتِ الصَّلاَةُ.
