Concerning speaking after the Imam comes down from the pulpit
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، عَنْ ثَابِتٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ كَانَ يُكَلَّمُ فِي الْحَاجَةِ إِذَا نَزَلَ عَنِ الْمِنْبَرِ يَوْمَ الْجُمُعَةِ .
It was narrated from Anas bin Malik that the people used to speak to the Prophet (ﷺ) about their needs when he came down from the pulpit on Friday.
