Halal (/həˈlɑːl/ ; Arabic: حلال ḥalāl [ħæˈlæːl]) is an Arabic word that translates to 'permissible' in English. Although the term halal is often associated with Islamic dietary laws, particularly meat that is slaughtered according to Islamic guidelines, it also governs ethical practices in business, finance (such as the prohibition of usury (riba)), and daily living. It encompasses broader ethical considerations, including fairness, social justice, and the treatment of animals. The concept of halal is central to Islamic practices and is derived from the Quran and the Sunnah (the teachings and practices of the Prophet Muhammad).
In the Quran, the term halal is contrasted with the term haram ('forbidden, unlawful'). The guidelines for what is considered halal or haram are laid out in Islamic jurisprudence (fiqh), and scholars interpret these guidelines to ensure compliance with Islamic principles. This binary opposition was elaborated into a more complex classification known as "the five decisions": mandatory, recommended, neutral, reprehensible and forbidden. Islamic jurists disagree on whether the term halal covers the first two or the first four of these categories. In recent times, Islamic movements seeking to mobilize the masses and authors writing for a popular audience have emphasized the simpler distinction of halal and haram.
