Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said to the delegation of Abd al-Qays: "I forbid you from hollowed tree-stump vessels, pitch-coated vessels, green jars, gourd vessels and the water-skin with its top cut off; rather, drink from your water-skin and tie its mouth."
In the narration of Abu Salih: Abu Hurayrah was asked: What is the hantam? He said: The green jar.
