Respect teachings of Prophet Muhammad; Be mindful when consuming food/drinks; Avoid unhealthy practices.

In this hadith narrated by Ibn 'Umar, it is reported that the Prophet Muhammad addressed people in one of his expeditions and forbade them from preparing a beverage called Nabidh in gourds or varnished jars. This hadith teaches us that we should be mindful of what we consume and how it is prepared. We should not prepare food or drinks with materials that are not suitable for consumption as they can be harmful to our health. Furthermore, this hadith also teaches us to respect the teachings of Prophet Muhammad and follow his instructions even if we do not understand why he has given them.
