Sunan Abi Dawud
حَدَّثَنَا مُوسَى، - يَعْنِي ابْنَ إِسْمَاعِيلَ - حَدَّثَنَا أَبَانُ، حَدَّثَنَا قَتَادَةُ، حَدَّثَنِي بَكْرُ بْنُ عَبْدِ اللَّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِهَذَا قَالَ " فِيهِمَا خَبَثًا " . قَالَ فِي الْمَوْضِعَيْنِ " خَبَثًا " .
This tradition has also been transmitted through a chain by Bakr b. ‘Abd Allah. This version has the word Khubuth (filth) and in two places the word Khubuthan (filth).
