حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحِ بْنِ الْمُهَاجِرِ، أَخْبَرَنَا اللَّيْثُ، عَنْ أَيُّوبَ بْنِ مُوسَى، عَنِ الأَسْوَدِ، بْنِ الْعَلاَءِ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ قَالَ " الْبِئْرُ جَرْحُهَا جُبَارٌ وَالْمَعْدِنُ جَرْحُهُ جُبَارٌ وَالْعَجْمَاءُ جَرْحُهَا جُبَارٌ وَفِي الرِّكَازِ الْخُمْسُ " .
