It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Avoid drinking from gourd vessels, green-glazed jars and pitch-coated vessels; drink from water-skins, and if you fear that it may ferment, dilute it with water."
