Musannaf Ibn Abi Shaybah

Hazrat Sha’bah says that I asked Hazrat Hakam and Hazrat Hammad whether the hair of a pig can be used for any purpose; they considered it undesirable.

Hazrat Abu Ja'far and Hasan have permitted the use of pig bristles in socks.

Hazrat Ibn Sirin did not use such socks in which pig's hair was used.

A certain elder from Wasit says that I asked Abu Ayyaz whether the hair of a pig can be placed on the wound of an animal; he declared it to be disliked (makruh).
