Hadith 4509

(حديث مرفوع) حَدَّثَنَا إِسْمَاعِيلُ ، أَخْبَرَنَا أَيُّوبُ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، أَنّ 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 " .
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Noble Prophet (peace and blessings be upon him) saw phlegm stuck towards the qiblah in the mosque. The Noble Prophet (peace and blessings be upon him) stood up and cleaned it, then turned towards the people and, being displeased with them, said: "When any one of you is in prayer, Allah is in front of his face, so none of you should clean his nose in front of his face during prayer."
