Muhammad bin 'Abdullah bin al-Zubair محمد بن عبد الله أبو أحمد الزبيري · Drinks (Kitab Al-Ashribah)

The Prophet (ﷺ) 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.
