Musannaf Ibn Abi Shaybah 26372 — Wearing fur

It is narrated from Thabit, who said: I was sitting with Abd al-Rahman bin Abi Layla when a big man with two braids came to him. He said to Ibn Abi Layla: "O Abu Isa!" He said: "Yes." He said: "Tell me what you have heard about fur garments." He said: I heard my father say: I was sitting in the company of the Prophet (peace and blessings be upon him). Meanwhile a man came to him (peace and blessings be upon him) and asked: "O Messenger of Allah (peace and blessings be upon him)! May I pray in a fur garment?" He (peace and blessings be upon him) said: "Where has the tanning gone?"
