Sunan Ibn Majah 733
The Book of the Adhan and the Sunnah Regarding It
If The Adhan Is Called And You Are In The Mosque, Then Do Not Leave
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ إِبْرَاهِيمَ بْنِ مُهَاجِرٍ، عَنْ أَبِي الشَّعْثَاءِ، قَالَ كُنَّا قُعُودًا فِي الْمَسْجِدِ مَعَ أَبِي هُرَيْرَةَ فَأَذَّنَ الْمُؤَذِّنُ فَقَامَ رَجُلٌ مِنَ الْمَسْجِدِ يَمْشِي فَأَتْبَعَهُ أَبُو هُرَيْرَةَ بَصَرَهُ حَتَّى خَرَجَ مِنَ الْمَسْجِدِ فَقَالَ أَبُو هُرَيْرَةَ أَمَّا هَذَا فَقَدْ عَصَى أَبَا الْقَاسِمِ ـ صلى الله عليه وسلم ـ .
It was narrated that Abu Sha'tha said: "We were sitting in the mosque with Abu Hurairah when the Mu'adh-dhin called the Adhan. A man got up and walked out of the mosque, and Abu Hurairah followed him with his gaze until he left the mosque. Then Abu Hurairah said: "This man has disobeyed Abul-Qasim.'"
