Narrated Salama bin Al-Muhabbiq:

Narrated (rad): Allah’s Messenger (ﷺ) said: “The tanning of a dead animal’s skin purifies it”. [Ibn Hibban graded it Sahih (sound)].

وَعَنْ سَلَمَةَ بْنِ الْمُحَبِّقِ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ الْلَّهِ ‏- صلى الله عليه وسلم ‏-{ دِبَاغُ جُلُودِ الْمَيْتَةِ طُهُورُهاَ } صَحَّحَهُ ابْنُ حِبَّانَ [1]‏ .‏
