Abdur Rahman bin Wa'lah says that I asked Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): "In our region, there is an abundance of grapes, and the most important commercial item there is wine." He replied: "There was a friend of the Prophet (peace be upon him) from the tribe of Daws. In the year of the conquest of Makkah, he came to meet the Prophet (peace be upon him) in Makkah and brought a waterskin of wine as a gift. The Prophet (peace be upon him) said to him: 'O Abu so-and-so! Do you not know that Allah has declared wine unlawful for you after you?' Upon hearing this, the man turned to his slave and whispered to him to take it and sell it. The Prophet (peace be upon him) asked him: 'What did you say to him?' He replied: 'I ordered him to go and sell it.' The Prophet (peace be upon him) said: 'The One who has forbidden its drinking has also forbidden its buying and selling.' So, upon his order, the wine was poured out."
