It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that I was an eyewitness to the delegation of Banu Abdul Qais. When those people came to the service of the Prophet (peace and blessings be upon him), the Prophet (peace and blessings be upon him) forbade them from drinking beverages in vessels called hantam, dubba, muzaffat, and naqir. Upon this, one of them stood up and said, "O Messenger of Allah! People have no other vessels besides these." I saw the Prophet (peace and blessings be upon him), and it seemed as if he felt sorry for the people. Then he said, "If these vessels are clean, then drink from them, and if they are dirty, then leave them."
