Sayyiduna Salamah bin Muhabbaq (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) came to a house during the expedition of Tabuk, where a water-skin was hanging in a corner. The Prophet (peace and blessings be upon him) asked for water, so it was submitted to him: This (water-skin) is made from the hide of a dead animal. The Prophet (peace and blessings be upon him) said: Tanning purifies the leather.
