فِي الرَّجُلِ يَطَأُ عَلَى الْمَوْضِعِ الَّذِي لَيْسَ بِنَظِيفٍ- ثُمَّ يَطَأُ بَعْدَهُ مَكَاناً نَظِيفاً قَالَ لَا بَأْسَ إِذَا كَانَ خَمْسَةَ عَشَرَ ذِرَاعاً أَوْ نَحْوَ ذَلِكَ.
“Abu ‘Abd Allah (a.s.), has said, ‘If one steps on a spot which is unclean, then steps on a clean spot, it is not harmful after walking a distance of fifteen yards or so.’”
