Abdur Rahman bin Wa'lah said: I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) about the skin of a dead animal, and he said: The Messenger of Allah (peace and blessings be upon him) said: "When it is tanned, it becomes purified." And I asked him (Ibn Abbas) about buying and selling wine with the people under protection (dhimmis), so he (Ibn Abbas) said: A man from the tribe of Banu Thaqif or Daws presented a wineskin to the Messenger of Allah (peace and blessings be upon him) during the Farewell Pilgrimage. The Prophet (peace and blessings be upon him) said to him: "O Abu So-and-so! Do you not know that Allah Almighty has forbidden wine?" He replied: "No, by Allah, I did not know." The Prophet (peace and blessings be upon him) said: "Then know that Allah Almighty has forbidden it." So the man turned to his servant and said: "Go, take it to Huzurah (a place name) and sell it." The Messenger of Allah (peace and blessings be upon him) said: "O Abu So-and-so! Do you not know that the One who has forbidden its drinking has also forbidden its selling?" The narrator said: So he ordered, and the wineskin was poured out in the open field.
