In page Sufism:

"

As a mystic and ascetic aspect of Islam, it is considered as the part of Islamic teaching that deals with the purification of the inner self. By focusing on the more spiritual aspects of religion, Sufis strive to obtain direct experience of God by making use of "intuitive and emotional faculties" that one must be trained to use.[4] Tasawwuf is regarded as a science of the soul that has always been an integral part of Orthodox Islam. In his Al-Risala al-Safadiyya, ibn Taymiyyah describes the Sufis as those who belong to the path of the Sunna and represent it in their teachings and writings.[citation needed]
