Hadith no. 1791 (below) is a repeat. Read it here.
Volume 3, Book 34, Number 296:
Narrated Hakim bin Hizam (radiallaahu `anhu):
The Prophet (sallallaahu `alayhi wasallam) said, “The buyer and the seller have the option to cancel or to confirm the deal, as long as they have not parted or till they part, and if they spoke the truth and told each other the defects of the things, then blessings would be in their deal, and if they hid something and told lies, the blessing of the deal would be lost.”
Trade of Alcohol:
Volume 3, Book 34, Number 297:
Narrated Aisha (radiallaahu `anhaa):
When the last verses of Surat al-Baqara were revealed, the Prophet (sallallaahu `alayhi wasallam) recited them in the mosque and proclaimed the trade of alcohol as illegal.
It is not permissible to deal in foods and other things, such as alcohol and pork, that Allaah has prohibited, even if one is selling to kaafirs, because it was reported that the Prophet (peace and blessings of Allaah be upon him) said: “When Allaah forbids a thing, He forbids its price.” And because he (peace and blessings of Allaah be upon him) cursed alcohol and the one who drinks it, the one who sells it, the one who buys it, the one who carries it, the one to whom it is carried, the one who consumes its price, the one who squeezes the grapes and the one for whom they are squeezed.
Must read: gradual prohibition of alcohol.
