وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ الْمَكِّيُّ، حَدَّثَنَا سُفْيَانُ، - هُوَ ابْنُ عُيَيْنَةَ - عَنْ عُمَرَ بْنِ سَعِيدٍ، عَنْ أَشْعَثَ بْنِ أَبِي الشَّعْثَاءِ الْمُحَارِبِيِّ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، وَرَأَى، رَجُلاً يَجْتَازُ الْمَسْجِدَ خَارِجًا بَعْدَ الأَذَانِ فَقَالَ أَمَّا هَذَا فَقَدْ عَصَى أَبَا الْقَاسِمِ صلى الله عليه وسلم .
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).
