(6) باب ذِكْرِ الْمَلاَئِكَةِ
Narrated Abu Huraira:
The Prophet (ﷺ) 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."
