عَنْ أَبِي هُرَيْرَةَ رضي الله عنه قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم: إِذَا كَانَ يَوْمُ الْجُمُعَةِ كَانَ عَلَى كُلِّ بَابٍ مِنْ أَبْوَابِ الْمَسْجِدِ الْمَلَائِكَةُ، يَكْتُبُونَ الأَوَّلَ فَالأَوَّلَ، فَإِذَا جَلَسَ الإِمَامُ طَوَوُا الصُّحُفَ وَجَاءُوا يَسْتَمِعُونَ الذِّكْرَ.
Hazrat Abu Hurairahra narrated, “The Prophetsa said, ‘When Friday arrives, the angels stand at every door of the mosque, writing down [those who arrive] first, then those after them in order. When the imam sits [to begin the sermon], they fold up their scrolls and come to listen to the remembrance.”
(Sahih al-Bukhari, Kitab Bad’i l-khalq, Bab dhikri l-mala’ikah, Hadith 3211)
