The distance between the Musalla of Messenger of Allah ﷺ and the wall was just sufficient for a sheep to pass through .  

كَانَ بَيْنَ مُصَلَّى رَسُولِ اللَّهِ ﷺ وَبَيْنَ الْجِدَارِ مَمَرُّ الشَّاةِ  

The distance between the wall of the mosque and the pulpit was hardly enough for a sheep to pass through.  

كَانَ جِدَارُ الْمَسْجِدِ عِنْدَ الْمِنْبَرِ مَا كَادَتِ الشَّاةُ تَجُوزُهَا
