Parts of the earth purify each other
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَرِيكٌ، عَنْ عَبْدِ اللَّهِ بْنِ عِيسَى، عَنْ مُوسَى بْنِ عَبْدِ اللَّهِ بْنِ يَزِيدَ، عَنِ امْرَأَةٍ، مِنْ بَنِي عَبْدِ الأَشْهَلِ قَالَتْ سَأَلْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ فَقُلْتُ إِنَّ بَيْنِي وَبَيْنَ الْمَسْجِدِ طَرِيقًا قَذِرَةً . قَالَ " فَبَعْدَهَا طَرِيقٌ أَنْظَفُ مِنْهَا " . قُلْتُ نَعَمْ . قَالَ " فَهَذِهِ بِهَذِهِ " .
It was narrated that a woman from (the tribe of) Banu 'Abdul-Ashhal said: "I said to the prophet: 'Between the mosque and I there is a filthy path.' He said: 'After that is there a cleaner path?' I said: 'Yes.' He said: 'This is (a remedy) for that.'"
