حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، وَمُوسَى بْنُ إِسْمَاعِيلَ، قَالاَ حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ جَوْنِ بْنِ قَتَادَةَ، عَنْ سَلَمَةَ بْنِ الْمُحَبَّقِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي غَزْوَةِ تَبُوكَ أَتَى عَلَى بَيْتٍ فَإِذَا قِرْبَةٌ مُعَلَّقَةٌ فَسَأَلَ الْمَاءَ فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّهَا مَيْتَةٌ . فَقَالَ " دِبَاغُهَا طُهُورُهَا " .
