حَدَّثَنَا بَهْزٌ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ حَدَّثَنَا زَيْدُ بْنُ أَسْلَمَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ وَعْلَةَ قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ قُلْتُ إِنَّا نَغْزُو هَذَا الْمَغْرِبَ وَأَكْثَرُ أَسْقِيَتِهِمْ جُلُودُ الْمَيْتَةِ قَالَ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ دِبَاغُهَا طُهُورُهَا
مسند امام احمد بن حنبل · Hadith 2538
It was narrated that 'Abdur- Rahman bin Wa'lah said: I asked Ibn 'Abbas (RA): We are campaigning against the people of the Maghrib and most of their waterskins are made from animals that were not slaughtered properly, He said: I heard the Prophet (PBUH) say: "Its tanning is its purification."
