Haram is an Arabic term meaning ‘forbidden’. This 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, in direct contrast, to an evil and thus "sinful action that is forbidden to be done". The term also denotes something "set aside", thus being the Arabic equivalent of the Hebrew concept קודש, qadoš and the concept of sacer in Roman law and religion. In Islamic jurisprudence, haram is used to refer to any act that is forbidden by Allah and is one of five Islamic commandments that define the morality of human action.
