The mind is one of the central concepts of philosophy. The mind usually refers to a collective form of intelligence and conscience. Which is published through thoughts, feelings, emotions, desires, and fantasies. Materialist philosophers believe that nothing is different from the mind and body of the person; Rather, the mind develops through physiological activities arising from the human brain. Really true definition of mind is not possible. But it can be said that the mind is something that is aware of its state and its activities.
In defining the mind of the Holy Qur'an, three types of minds have been mentioned. The first is the calm mind; The second is a repentant mind, And the third is the ghost or evil mind. In these three types of mind, the best mind to the creator is the calm mind.
