Arabic

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، وَأَبَا، سَعِيدٍ أَخْبَرَاهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى نُخَامَةً فِي حَائِطِ الْمَسْجِدِ، فَتَنَاوَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم حَصَاةً فَحَتَّهَا ثُمَّ قَالَ ‏ "‏ إِذَا تَنَخَّمَ أَحَدُكُمْ فَلاَ يَتَنَخَّمْ قِبَلَ وَجْهِهِ وَلاَ عَنْ يَمِينِهِ، وَلْيَبْصُقْ عَنْ يَسَارِهِ، أَوْ تَحْتَ قَدَمِهِ الْيُسْرَى ‏"‏‏.‏
