I have a very simple question, I want to know why do Muslims eat halal food and halal meat.
Halal is an Arabic word which when translated means lawful/permissible and is a word applied to all aspects of life. The opposite is Haram. Muslims are ordained in the Holy Quran to consume halal, and Tayyiban foods.
