Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ أَخْبَرَنَا أَيُّوبُ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى نُخَامَةً فِي قِبْلَةِ الْمَسْجِدِ فَقَامَ فَحَكَّهَا أَوْ قَالَ فَحَتَّهَا بِيَدِهِ ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَتَغَيَّظَ عَلَيْهِمْ وَقَالَ إِنَّ اللَّهَ عَزَّ وَجَلَّ قِبَلَ وَجْهِ أَحَدِكُمْ فِي صَلَاتِهِ فَلَا يَتَنَخَّمَنَّ أَحَدٌ مِنْكُمْ قِبَلَ وَجْهِهِ فِي صَلَاتِهِ.
English Translation
Isma'il told us, Ayyub informed us, from Nafi', from Ibn Umar: that the Prophet, peace and blessings be upon him, saw phlegm on the qibla wall of the mosque, so he stood up and scraped it - or he said removed it - with his hand, then turned to the people, angry with them, and said: "Indeed, Allah, Mighty and Majestic, is before the face of one of you during his prayer, so let none of you spit before his face during his prayer."
