(29) بَابُ إِذَا اخْتَلَفُوا فِي الطَّرِيقِ الْمِيتَاءِ- وَهْيَ الرَّحْبَةُ تَكُونُ بَيْنَ الطَّرِيقِ- ثُمَّ يُرِيدُ أَهْلُهَا الْبُنْيَانَ، فَتُرِكَ مِنْهَا الطَّرِيقُ سَبْعَةَ أَذْرُعٍ
Narrated Abu Huraira:
The Prophet (ﷺ) judged that seven cubits should be left as a public way when there was a dispute about the land.
