[Machine] The Prophet ﷺ was delivering a sermon when he noticed a stain on the Qibla side of the mosque and became angry with the people of the mosque. Then he said, "Indeed, Allah, the Exalted, faces one of you when he prays, so let him not spit or blow his nose. Then he descended and wiped it with his hand, then he smeared it with what I think was saffron." Ibn Umar said, "When one of you blows his nose, let him blow it with his left hand."  

أَنَّ النَّبِيَّ ﷺ بَيْنَمَا هُوَ يَخْطُبُ إِذْ رَأَى نُخَامَةً فِي قِبْلَةِ الْمَسْجِدِ فَتَغَيَّظَ عَلَى أَهْلِ الْمَسْجِدِ ثُمَّ قَالَ إِنَّ اللهَ تَعَالَى قِبَلَ أَحَدِكُمْ إِذَا صَلَّى فَلَا يَبْزُقَنَّ أَوْ لَا يَتَنَخَّمَنَّ ثُمَّ نَزَلَ فَحَتَّهُ بِيَدِهِ ثُمَّ لَطَخَهُ فِيمَا أَظُنُّهُ بِزَعْفَرَانٍ وَقَالَ ابْنُ عُمَرَ إِذَا تَنَخَّعَ أَحَدُكُمْ فَلْيَتَنَخَّعْ عَنْ يَسَارِهِ
