Seek advice from knowledgeable people before consuming food or drinks

In this hadith, Al-Hasan is advising against drinking thickened grape juice that has been reduced to half. This type of drink can be dangerous and unhealthy for the body. It is important to remember that even if something looks or tastes good, it may not always be beneficial for our health. We should always take care when consuming food and drinks and make sure we are aware of the potential risks associated with them. It is also important to seek advice from knowledgeable people such as Al-Hasan in order to ensure we are making informed decisions about what we consume.
