What was narrated concerning facing the Imam when he is delivering the sermon

It was narrated from ‘Adi bin Thabit that his father said:
“When the Prophet ﷺ stood on the pulpit, his Companions would turn to face him.”

حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا الْهَيْثَمُ بْنُ جَمِيلٍ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ أَبَانَ بْنِ تَغْلِبَ، عَنْ عَدِيِّ بْنِ ثَابِتٍ، عَنْ أَبِيهِ، قَالَ كَانَ النَّبِيُّ ﷺ إِذَا قَامَ عَلَى الْمِنْبَرِ اسْتَقْبَلَهُ أَصْحَابُهُ بِوُجُوهِهِمْ .
