English translation
1728. Ibn ‘Abbās narrated that the Messenger of Allāh ﷺ said: “Any skin that is tanned, then it has been made pure.” (Ṣaḥīḥ) This Hadīth is Hasan Ṣaḥīḥ. 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. [Abū 'Eisā said:] Ash-Shāfi'ī said: "Any [dead animal's] 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 'Abdullāh bin Al-Mubārak, Aḥmad, and Ishāq], and they were firm about not wearing them and performing Ṣalāt in them. Ishāq bin Ibrāhīm 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-Naṣr bin Shumail. And he said: "The word Ihāb is only used for a skin of an animal that is eaten," and Ibn al-Mubārak, Aḥmad, Ishāq and Al-Ḥumaidī disliked performing Ṣalāt in predator skins.
