Halal, also spelled hallal or halaal, refers to what is permissible or lawful in traditional Islamic law. It is frequently applied to permissible food and drinks.
What is HALAL?
Haram is an Arabic term meaning "forbidden". Thus it may refer to: either something sacred to which access is forbidden to the people who are not in a state of purity or who are not initiated into the sacred knowledge; or to an evil thus "sinful action that is forbidden to be done".
Prohibited because of its essence and harm it causes to an individual.
Prohibited because of external reasons that are not fundamentally harmful but are associated to something that is prohibited.
