Hadith 58

Sahih Bukhari

Book 11: Friday Prayer

Chapter 36

One should keep quiet and listen while the Imam is delivering the Khutba

باب الإِنْصَاتِ يَوْمَ الْجُمُعَةِ وَالإِمَامُ يَخْطُبُ

And if a person says to his companion: "Be quiet and listen," even then he is doing something wrong (which will reduce his reward). Narrated Salman: The Prophet ﷺ said, "Whenever the Imam is delivering the Khutba (religious talk), it is essential for the audience to keep quiet and listen." ​​
وَإِذَا قَالَ لِصَاحِبِهِ أَنْصِتْ. فَقَدْ لَغَا. وَقَالَ سَلْمَانُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُنْصِتُ إِذَا تَكَلَّمَ الإِمَامُ.
Sahih al-Bukhari 934
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، أَنَّ أَبَا هُرَيْرَةَ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ ‏‏.‏
"‏ إِذَا قُلْتَ لِصَاحِبِكَ يَوْمَ الْجُمُعَةِ أَنْصِتْ‏.‏ وَالإِمَامُ يَخْطُبُ فَقَدْ لَغَوْتَ ‏"
Abu Huraira:

Allah's Messenger (ﷺ) (p.b.u.h) said, "When the Imam is delivering the Khutba, and you ask your companion to keep quiet and listen, then no doubt you have done an evil act."
