A man of the deputation of Abd al-Qais who came to the Prophet صلی اللہ علیہ وسلم said - the narrator Awf thinks that his name was Qais bin al-Numan: The Prophet صلی اللہ علیہ وسلم said: Do not drink from hollowed stumps, vessel smeared with pitch, pumpkins, and green jars, but drink from a skin which is tied with string. If the drink ferments, lighten it by infusing water. If you are helpless, then pour it away.
