Abdur Rahman bin Wa'lah says that I asked Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) about the issue of trading in alcohol. He replied that in the tribe of Thaqif or Daws, the Prophet (peace and blessings be upon him) had a friend who, in the year of the conquest of Makkah, came to meet the Prophet (peace and blessings be upon him) in Makkah and brought a waterskin of alcohol as a gift. The Prophet (peace and blessings be upon him) said to him: "O Abu so-and-so! Do you not know that Allah has declared alcohol to be forbidden?" Upon hearing this, the man turned to his slave and whispered to him to take it and sell it. The Prophet (peace and blessings be upon him) asked him, "O Abu so-and-so! What did you say to him?" He replied, "I ordered him to go and sell it." The Prophet (peace and blessings be upon him) said: "The One who has forbidden its consumption has also forbidden its buying and selling." Thus, on his order, the alcohol was poured out in the valley of Batha.
