Arabic (Original)
حَدَّثَنَا عَبْدُ الْوَهَّابِ عَنْ سَعِيدٍ عَنْ قَتَادَةَ عَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ النُّخَاعَةُ فِي الْمَسْجِدِ خَطِيئَةٌ وَكَفَّارَتُهَا دَفْنُهَا.
English Translation
Abd al-Wahhab told us, from Sa'id, from Qatada, from Anas, that the Prophet, peace and blessings be upon him, said: 'Phlegm in the mosque is a sin, and its expiation is burying it.'
