Some Sufis are people of goodness and merit as the concept of Sufism to them is asceticism with regard to worldly pleasures and devotion to good doing in preparation for the Hereafter. There are other Sufis, however, who follow religious innovations and myths, and some even fall into polytheism and deviation; may Allah safeguard us.

Indeed beliefs collide mainly with the essence of Islam ..
We must warn them because they are against the teachings of Islam

Later on, Sufism became a mixture of various innovations and exaggerations. Many forbidden ideologies of philosophers found their ways into it, such as pantheism, immanentism and atheism, which assert that one becomes free from following Islam (i.e., not obligated by it) after reaching a prescribed stage. There is no doubt that contemporary Sufism contains many deviations such as exaggerating the status of Shaykhs and the pious and worshipping tombs and graves by making sacrifices therein and supplication and circumambulation. The Sufis worship the inhabitants of these by asking for their help and support, and this is major Shirk (polytheism) and


Allaah never forgives this kind of Shirk. Moreover, they adhere to many invented supplications and celebrate the birthday of the Prophet sallallaahu `alayhi wa sallam ( may Allaah exalt his mention ) and others. Pantheism and immanentism still exist in many groups of Sufis.

Allaah Knows best.
