عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ “‏ إِذَا كَانَ يَوْمُ الْجُمُعَةِ كَانَ عَلَى كُلِّ باب مِنْ أَبْوَابِ الْمَسْجِدِ الْمَلاَئِكَةُ، يَكْتُبُونَ الأَوَّلَ فَالأَوَّلَ، فَإِذَا جَلَسَ الإِمَامُ طَوَوُا الصُّحُفَ وَجَاءُوا يَسْتَمِعُونَ الذِّكْرَ ‏”‏‏

Sahih al-Bukhari 3211

Narrated Abu Hurairaؓ that The Prophetﷺ said, “On every Friday the angels take their stand at every gate of the mosque to write the names of the people chronologically (i.e. according to the time of their arrival for the Friday prayer) and when the Imam sits (on the pulpit) they fold up their scrolls and get ready to listen to the sermon.”
