Refering to the domain of knowledge, adab means an intellectual discipline (ketertiban budi) which recognizes and acknowledges the hierarchy of knowledge based on the criteria of degrees of perfection (keluhuran) and priority (keutamaan) such that the ones that are based on revelation are recognized and acknowledged as more perfect and of a higher priority than those based on the intellect; those that are fard 'ayn are above fard kifayah; those that provide guidance (hidayah) to life are more superior to those that are practically useful (kegunaan amali). Adab towards knowledge would result in the proper and correct ways of learning and applying different sciences.
