"This book is of great value for those in pursuit of the purification of the heart in preperation for the hereafter which should be the objective for every Muslim."

The Muslim World Book Review

The Qur'an and Hadith refer to the heart as an organ of understanding, thinking and feeling.

This book begins by examining the 'intelligence' of the heart according to the Qur'an and hadith and shows how science is only now beginning to discover what has been known to Muslims for over 1400 years.
