عَنْ أَبِي هُرَيْرَةَ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ: إِذَا قُلْتَ لِصَاحِبِكَ يَوْمَ الْجُمُعَةِ أَنْصِتْ وَالإِمَامُ يَخْطُبُ فَقَدْ لَغَوْتَ.
Hazrat Abu Hurairahra narrated that Allah’s Messngersa said, “If you say to your companion, on Friday, while the imam is delivering the sermon [khutbah], ‘Keep quiet’, then you too have engaged in idle talk.”
(Sahih al-Bukhari, Kitab al-jumu‘ah, Bab al-insati yawma al-jumu‘ati wa al-imamu yakhtub, Hadith 934)
