It is narrated from Sayyiduna Salamah bin al-Muhabbiq (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) came to a house, and in front of him a waterskin was hanging. The Prophet (peace and blessings be upon him) asked for water, and they said: It is made from the skin of a carcass. He (peace and blessings be upon him) said: "Its purification is its tanning."
Hammam bin Yahya said: Its tanning is its purification.
