وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا وَطِئَ أَحَدُكُمْ بِنَعْلِهِ الْأَذَى فَإِنَّ التُّرَابَ لَهُ طَهُورٌ»
Abu Hurayrah reported God’s messenger as saying, “When any of you treads with his sandal on something unclean, earth should be used to purify it.”
