Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ يَزِيدَ عَنْ هِشَامٍ الدَّسْتُوَائِيِّ وَشُعْبَةَ جَمِيعًا عَنْ قَتَادَةَ عَنْ أَنَسِ بْنِ مَالِكٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْبُزَاقُ فِي الْمَسْجِدِ خَطِيئَةٌ وَكَفَّارَتُهَا دَفْنُهَا.
English Translation
Muhammad ibn Yazid told us, from Hisham al-Dastuwa'i and Shu'ba together, from Qatada, from Anas ibn Malik, from the Prophet, peace and blessings be upon him, who said: 'Spitting in the mosque is a sin, and its expiation is burying it.'
