Arabic (Original)
حَدَّثَنَا إِبْرَاهِيمُ بْنُ أَبِي الْعَبَّاسِ حَدَّثَنَا أَبُو أُوَيْسٍ عَنِ الزُّهْرِيِّ أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ أَخْبَرَهُ أَنَّ أَبَا هُرَيْرَةَ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِذَا قُلْتَ لِصَاحِبِكَ أَنْصِتْ وَالْإِمَامُ يَخْطُبُ فَقَدْ لَغَوْتَ.
English Translation
Ibrahim ibn Abi al-'Abbas narrated to us, Abu Uways narrated to us, from al-Zuhri, that Sa'id ibn al-Musayyab informed him that Abu Hurayrah said: I heard the Messenger of Allah (peace be upon him) say: "If you say to your companion 'Be quiet' while the imam is delivering the sermon (on Friday), you have engaged in idle speech."
