"‏ إِذَا كَانَ يَوْمُ الْجُمُعَةِ غَدَتِ الشَّيَاطِينُ بِرَايَاتِهَا إِلَى الأَسْوَاقِ فَيَرْمُونَ النَّاسَ بِالتَّرَابِيثِ أَوِ الرَّبَائِثِ وَيُثَبِّطُونَهُمْ عَنِ الْجُمُعَةِ وَتَغْدُو الْمَلاَئِكَةُ فَيَجْلِسُونَ عَلَى أَبْوَابِ الْمَسْجِدِ فَيَكْتُبُونَ الرَّجُلَ مِنْ سَاعَةٍ وَالرَّجُلَ مِنْ سَاعَتَيْنِ حَتَّى يَخْرُجَ الإِمَامُ فَإِذَا جَلَسَ الرَّجُلُ مَجْلِسًا يَسْتَمْكِنُ فِيهِ مِنَ الاِسْتِمَاعِ وَالنَّظَرِ فَأَنْصَتَ وَلَمْ يَلْغُ كَانَ لَهُ كِفْلاَنِ مِنْ أَجْرٍ فَإِنْ نَأَى وَجَلَسَ حَيْثُ لاَ يَسْمَعُ فَأَنْصَتَ وَلَمْ يَلْغُ كَانَ لَهُ كِفْلٌ مِنْ أَجْرٍ وَإِنْ جَلَسَ مَجْلِسًا يَسْتَمْكِنُ فِيهِ مِنَ الاِسْتِمَاعِ وَالنَّظَرِ فَلَغَا وَلَمْ يُنْصِتْ كَانَ لَهُ كِفْلٌ مِنْ وِزْرٍ وَمَنْ قَالَ يَوْمَ الْجُمُعَةِ لِصَاحِبِهِ صَهْ ‏.‏ فَقَدْ لَغَا وَمَنْ لَغَا فَلَيْسَ لَهُ فِي جُمُعَتِهِ تِلْكَ شَىْءٌ ‏"

Ali said on the pulpit in the mosque of Kufah: When Friday comes, the devils go to the markets with their flags, and involve people in their needs and prevent them from the Friday prayer. The angels come early in the morning, sit at the door of the mosque, and record that so-and-so came at the first hour, and so-and-so came at the second hour until the imam comes out (for preaching). When a man sits in a place where he can listen (to the sermon) and look (at the imam), where he remains silent and does not interrupt, he will receive a double reward. If he stays away, sits in a place where he cannot listen (to the sermon), silent, and does not interrupt, he will receive the reward only once. If he sits in a place where he can listen (to the sermon) and look (at the imam), and he does not remain silent, he will have the burden of it. If anyone says to his companion sitting besides him to be silent (while the imam is preaching), he is guilty of idle talk. Anyone who interrupts (during the sermon) will receive nothing (no reward) on that Friday. Then he (the narrator) says in the end of this tradition: I heard the Messenger of Allah (ﷺ) say so. Abu Dawud said: This tradition has been narrated by al-Walid b. Muslim from Ibn Jabir. This version adds: bi'l-raba'ith (instead of al-raba'ith, needs preventing the people from prayer). Further, this adds: Freed slave of his wife Umm 'Uthman b. 'Ata.
