Ruling on praying in fox fur

Hazrat Anas bin Malik (may Allah be pleased with him) narrates that once Hazrat Umar bin Khattab saw a man praying while wearing a cap made from fox skin. He removed the cap from the man's head and said, "Who knows, perhaps it was not slaughtered (properly)?"

Hazrat Ali (may Allah be pleased with him) considered it disliked to pray in a fox's skin.

Hazrat Saeed bin Jubair and Hasan say that wear garments made from fox skin, but do not pray in them.

Hasan did not consider there to be any harm in wearing clothing made from fox skin, provided that it had been tanned.

Hazrat Amr bin Saeed says that Hazrat Abu Aliah once entered the mosque, and he was wearing a cap made of fox skin on his head. When he began to pray, he took off this cap and placed it in his sleeve. When he completed the prayer, I asked him, "Why did you take off your cap and put it in your sleeve?" He replied, "I did not like to pray in it, nor was I willing to leave it aside lest it be stolen. Therefore, I put it in my sleeve."

Hazrat Abu Ja'far narrates that Hazrat Ali bin Husayn (may Allah be pleased with him) had a sky-colored garment made from fox skin. When he would begin to pray, he would take it off.
