Abu Sha'tha' reported
While we were sitting with Abu Huraira in a mosque a man went out of the mosque after the call to prayer had been announced. (A man stood up in the mosque and set off.) Abu Huraira's eyes followed him till he went out of the mosque. Upon this Abu Huraira said: This man has disobeyed Abu'l- Qasim (Muhammad) (ﷺ).
Abu Sha'tha' al-Muharibi reported on the authority of his father, who said
I heard it from Abu Huraira that he saw a person getting out of the mosque after the call to prayer had been announced. Upon this he remarked: This (man) disobeyed Abu'l-Qasim (ﷺ).
