Abstract: The Aim of the prophets’ mission and revelation of the Holy Qur’an is to train an individual and develop a healthy personality by forming a constructive relationship with God, one’s self, society, and the environment. In order to achieve this scared purpose, humankind is granted revelatory teachings of the Qur’an and narrations from the Infallibles. According to Islamic teachings, without the connection with God, any claim to have a healthy personality is unfounded. A Person’s mental health is measured by his distance from or closeness to God. This article describes the concept of a healthy personality and its outcomes, with an explanation on the relationship of the healthy personality with prayer and servitude to God. Among the salient points of this article is the concept of personality in psychology and the role of a healthy personality in the observance of Islamic values.
