11.36 One should keep quiet and listen while the Imam is delivering the Khutba
١١۔٣٦ باب الإِنْصَاتِ يَوْمَ الْجُمُعَةِ وَالإِمَامُ يَخْطُبُ
[Machine] "When he says to his companion, 'Be quiet', he has certainly exceeded the limits. Salman reported from the Prophet ﷺ that one should be attentive when the Imam speaks."
وَإِذَا قَالَ لِصَاحِبِهِ أَنْصِتْ. فَقَدْ لَغَا. وَقَالَ سَلْمَانُ عَنِ النَّبِيِّ ﷺ يُنْصِتُ إِذَا تَكَلَّمَ الإِمَامُ.
