Sahih Muslim , Hadith 508 ⓘ
Sahl b. Sa'd al-Si'idi reported: Between the place of worship where the Messenger of Allah prayed and the wall, there was a gap through which a goat could pass.
حَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ، حَدَّثَنَا ابْنُ أَبِي حَازِمٍ، حَدَّثَنِي أَبِي، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، قَالَ كَانَ بَيْنَ مُصَلَّى رَسُولِ اللَّهِ صلى الله عليه وسلم وَبَيْنَ الْجِدَارِ مَمَرُّ الشَّاةِ .
