Based on Islamic law, halal is a term that is used to describe and define not only food and drink but also all matters of daily life. Mostly, halal is referred to food that is allowed for Muslims to eat or drink. The most common food which is not permissible for Muslims is pork, but food other that pork can be restricted as well. It must come from a supplier that uses halal practices, for instance, the slaughter must be performed by a Muslim. Furthermore, all non-food items like cosmetics and pharmaceuticals must comply with the regulation as mentioned previously as well.
