ذِكْرُ الْإِبَاحَةِ لِلْمُصَلِّي أَنْ يَبْصُقَ فِي نَعْلَيْهِ أَوْ يَتَنَخَّعَ فِيهِمَا
'Abdullah b. Shakhkhir narrated it on the authority of his father that he said prayer with the Messenger of Allah ﷺ, and he spat and then rubbed it off with his left shoe. (Using translation from Muslim 554b)
«أَنَّهُ صَلَّى مَعَ رَسُولِ اللَّهِ ﷺ فَتَنَخَّعَ فَدَلَكَهَا بِنَعْلِهِ الْيُسْرَى»
