Avoid blowing into drinking vessels

The Prophet Muhammad (peace be upon him) taught us to avoid blowing into a drinking vessel. This is because when we blow into a container of liquid, we are introducing our saliva and breath which can contain germs and bacteria that can contaminate the drink. Therefore, it is important to keep our drinks clean and free from any contamination by avoiding this practice. Additionally, this hadith teaches us to take care of our health by being mindful of what we put in our bodies and how we handle food items. It also encourages us to think about how our actions may affect others if they were to consume something that has been contaminated by us.
