The behavioural disposition (nafsiyyah) is the method for satisfying man's instincts and organic needs i.e. the manner in which they are satisfied according to a standard which man believes in and trusts. When the satisfaction is based on the Islamic Aqidah then he has an Islamic disposition, if not he has a disposition other than the Islamic behavioural disposition. If a person has one standard for the mentality and behavioural disposition, then his personality becomes distinctive and regulated. If the Islamic 'Aqidah was the basis of his mentality and behavioural disposition, his personality would be Islamic. If not, then his personality would be something else. The book seeks to help the Mumineen reaffirm their Iman in Allah such that their tongues are moist with the remembrance of Allah (swt), their hearts are filled with the fear of Allah (swt) and that their limbs hasten towards the good deeds. It guides the reader with various principles in forming the Islamic Nafsiya and the styles to achieve the correction visualization of the Islamic concepts.
