To scrape the nasal secretion off the mosque with gravel

باب حَكِّ الْمُخَاطِ بِالْحَصَى مِنَ الْمَسْجِدِ

And Ibn 'Abbas said, "If you tread on (any) wet, filthy thing, wash it away and if it is dry don't wash it."
وَقَالَ ابْنُ عَبَّاسٍ إِنْ وَطِئْتَ عَلَى قَذَرٍ رَطْبٍ فَاغْسِلْهُ، وَإِنْ كَانَ يَابِسًا فَلاَ.
Sahih al-Bukhari 408, 409
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ أَخْبَرَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، أَخْبَرَنَا ابْنُ شِهَابٍ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، وَأَبَا، سَعِيدٍ حَدَّثَاهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى نُخَامَةً فِي جِدَارِ الْمَسْجِدِ، فَتَنَاوَلَ حَصَاةً فَحَكَّهَا فَقَالَ ‏ ‏‏.‏
"‏ إِذَا تَنَخَّمَ أَحَدُكُمْ فَلاَ يَتَنَخَّمَنَّ قِبَلَ وَجْهِهِ وَلاَ عَنْ يَمِينِهِ، وَلْيَبْصُقْ عَنْ يَسَارِهِ أَوْ تَحْتَ قَدَمِهِ الْيُسْرَى ‏"
Abu Huraira and Abu Sa`id:

Allah's Messenger (ﷺ) saw some expectoration on the wall of the mosque; he took gravel and scraped it off and said, "If anyone of you wanted to spit he should neither spit in front of him nor on his right but he could spit either on his left or under his left foot."
