The Purification of the Soul
the concept of purification of the soul as a whole is and always will be central to the message of Islam and to the welfare of humans, both in this life and the Hereafter. Indeed, it was a main mission of the messengers and prophets themselves. The path described by the Quran and Sunnah is the only path that can result in a true purification of the soul. Indeed, it is the only path that is truly consistent with the purpose for which humans were created. Hence, any discussion of purification of the soul must rely heavily and exclusively on the Qruan and Sunnah and what can be correctly derived from those two sources.
