عَفَّانُ ، حَدَّثَنَا
وُهَيْبٌ ، حَدَّثَنَا
سُهَيْلٌ ، عَنْ
أَبِيهِ ، عَنْ
أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ , قَالَ :
" إِذَا تَكَلَّمْتَ يَوْمَ الْجُمُعَةِ فَقَدْ لَغَوْتَ ، وَأَلْغَيْتَ " .
It is narrated with the previous chain that the Noble Prophet (peace and blessings be upon him) said: When the Imam is delivering the Friday sermon and you speak to your companion, then you have engaged in idle talk and rendered it void.
