Ibn ‘Abbas reported God’s Messenger as saying, “If anyone speaks on Friday while the imam is preaching, he is like an ass which carries books, (cf. Al-Qur'an; 62:5) and he who tells him to be quiet is not credited with the Friday prayer.” Ahmad transmitted it.
وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ تَكَلَّمَ يَوْمَ الْجُمُعَةِ وَالْإِمَامُ يَخْطُبُ فَهُوَ كَمَثَلِ الْحِمَارِ يَحْمِلُ أَسْفَارًا وَالَّذِي يَقُولُ لَهُ أَنْصِتْ لَيْسَ لَهُ جُمُعَة» . رَوَاهُ أَحْمد
