Narrated Ibn 'Abbas:

That the Messenger of Allah ﷺ said: "Any skin tanned, then it has been made pure."

This Hadith is Hasan Sahih. This is acted upon according to most of the people of knowledge, they say that when the skin of a dead animal has been tanned then it has been made pure.

[Abu 'Eisa said:] Ash-Shafi'i said: "Any dead animals skin that is tanned, then it has been made pure, except for the dog and the pig." Some of the people of knowledge among the Companions of the Prophet ﷺ disliked skins of predators even when tanned, and this is the view of 'Abdullah bin Al-Mubarak, Ahmad and Ishaq, and they were firm about not wearing them and performing Salat in them. Ishaq bin Ibrahim said: "The saying of the Prophet ﷺ:'Any skin that is tanned, then it has been made pure' only refers to the skins of animals whose meat is eaten." This is how it was explained by An-Nasr bin Shumail.

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، وَعَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ وَعْلَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " أَيُّمَا إِهَابٍ دُبِغَ فَقَدْ طَهُرَ " . هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ . وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَكْثَرِ أَهْلِ الْعِلْمِ قَالُوا فِي جُلُودِ الْمَيْتَةِ إِذَا دُبِغَتْ فَقَدْ طَهُرَتْ .

قَالَ أَبُو عِيسَى قَالَ الشَّافِعِيُّ أَيُّمَا إِهَابِ مَيْتَةٍ دُبِغَ فَقَدْ طَهُرَ إِلاَّ الْكَلْبَ وَالْخِنْزِيرَ . وَاحْتَجَّ بِهَذَا الْحَدِيثِ . وَقَالَ بَعْضُ أَهْلِ الْعِلْمِ مِنْ أَصْحَابِ النَّبِيِّ ﷺ وَغَيْرِهِمْ إِنَّهُمْ كَرِهُوا جُلُودَ السِّبَاعِ وَإِنْ دُبِغَ وَهُوَ قَوْلُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ وَأَحْمَدَ وَإِسْحَاقَ وَشَدَّدُوا فِي لُبْسِهَا وَالصَّلاَةِ فِيهَا . قَالَ إِسْحَاقُ بْنُ إِبْرَاهِيمَ إِنَّمَا مَعْنَى قَوْلِ رَسُولِ اللَّهِ ﷺ " أَيُّمَا إِهَابٍ دُبِغَ فَقَدْ طَهُرَ " . جِلْدُ مَا يُؤْكَلُ لَحْمُهُ هَكَذَا فَسَّرَهُ النَّضْرُ بْنُ شُمَيْلٍ . وَقَالَ إِسْحَاقُ قَالَ النَّضْرُ بْنُ شُمَيْلٍ إِنَّمَا يُقَالُ الإِهَابُ لِجِلْدِ مَا يُؤْكَلُ لَحْمُهُ .
