This hadith is about a group of people from the tribe of 'Abd al-Qais who asked Allah's Messenger about vessels which might be used for preparing Nabidh and drinking in them. The Prophet forbade them to use gourds, hollow stumps, or vessels besmeared with pitch. He also mentioned that he did not hear him mention varnished jars on that day but he hated it anyway. This hadith teaches us that we should be careful when choosing what kind of vessel to use when preparing food or drinks as some materials are prohibited by Islam due to their potential harm to our health or hygiene. It also teaches us respect towards our elders as we can see how Sa'id b. Musayyib asked 'Abdullah b 'Umar if he forgot something while narrating this hadith out of respect towards him even though he was younger than him in age.
