Sahih al-Bukhari, Volume 9, Book 92, Hadith 434 (USC-MSA) ⓘ
Narrated Sahl: The distance between the pulpit and the wall of the mosque on the side of the Qibla was just sufficient for a sheep to pass through.
حَدَّثَنَا ابْنُ أَبِي مَرْيَمَ، حَدَّثَنَا أَبُو غَسَّانَ، حَدَّثَنِي أَبُو حَازِمٍ، عَنْ سَهْلٍ، أَنَّهُ كَانَ بَيْنَ جِدَارِ الْمَسْجِدِ مِمَّا يَلِي الْقِبْلَةَ وَبَيْنَ الْمِنْبَرِ مَمَرُّ الشَّاةِ.
