Though Counselling is, in its professional sense, a new phenomenon and is considered as one of the achievements of modern psychology in the western world in the last century, it has been used and emphasized widely by Islam - as it was crystalized in the life-style of the Infallibles - to mean guiding people and seeking help from authorities. Islam, as a comprehensive and all-embracing religion has given tremendous importance to the mental health of human beings, paving the way for its fulfilment by providing necessary plans and precepts, and it is from the very standpoint that the problem of consultation and psychotherapy can be taken into consideration. This article explains the concept of Counselling and its conceptual differences from the viewpoint of modern psychology as well as of Islam, arguing that Islam is not, in fact, a consultative school or theory; rather it is a comprehensive intellectual, doctrinal and behavioural system of thought which has determined the overal framework of man's life and the ways to the attainment of happiness and salvation, and that consultation, like any other human affairs, is to adapt its principles and methods to the objectives, values, norms and programmes as well as duties (obligations) set forth in Islamic communities.
