حَدَّثَنَا يَعْلَى ، عَنْ مُحَمَّدِ بْنِ إِسْحَاق ، عَنْ الْقَعْقَاعِ بْنِ حَكِيمٍ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ وَعْلَةَ ، قَالَ : سَأَلْتُ ابْنَ عَبَّاسٍ عَنْ جُلُودِ الْمَيْتَةِ، فَقَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" دِبَاغُهَا طَهُورُهَا ".
قِيلَ لِأَبِي مُحَمَّدٍ عَبْدِ اللَّهِ : تَقُولُ بِهَذَا؟ قَالَ : نَعَمْ، إِذَا كَانَ يُؤْكَلُ لَحْمُهُ

Ya’la told us, on the authority of Muhammad bin Ishaq, on the authority of Al-Qaqa’ bin Hakim, on the authority of Abd al-Rahman bin Wa’ala, he said: I asked Ibn Abbas about The skins of dead animals, and he said: The Messenger of God, may God bless him and grant him peace, said: “Tanning them purifies them.”
It was said to Abu Muhammad Abdullah: Do you say this? He said: Yes, if his meat is eaten.
