In any case...
In any case, these ideas are a form of deviation from Islam and the proper Shi‘a creeds. Such beliefs have more often been found among the Sufis, most of who are considered among the Ahl al-Sunnat; ideas such as transmigration ( hulul ), unity ( ittihad ), and so forth tend to be found in their writings.
Fortunately, thanks to the guidance of the Imams (peace be upon them), not only did the issue of sufism not spread as much among the Shi‘a as among the Ahl al-Sunnat, rather it was also repudiated and condemned by the Imams (peace be upon them), their followers, and the major scholars.
Thus, associating these issues to the Shi‘a is slander; the Shi‘a beliefs in regard to each of the issues of Divine unity, prophecy, Imamah , and resurrection are free of such exaggerated and devious matters, since the Imams (peace be upon them) as protectors of the Divine religion acted in such a way over two and half centuries as to close the path for idolatrous beliefs to penetrate, and the limits and boundaries of the fundamentals of Shi‘a thought and doctrine became known.
Afterwards, the scholars clearly explained all of these beliefs by compiling and writing books of doctrine, such as the I`tiqadat of Majlisi. A small group of Sufis was indeed found among the Shi‘a who put forth exaggerated beliefs in the name of wilayah and love of ‘Ali (peace be upon him), and in every case with the efforts of the mindful ‘Ulama appropriate answers were given them. As a result, they were not able to offer much resistance.
The Shi‘a consider none a partner to Allah in the His qualities of Majesty and Beauty. They believe the Prophet and Imams (peace be upon them) to be creatures and worshippers of Allah who are in need of Allah from all aspects and regard only Allah as free of need by His essence.
Of course, the qualities, distinctions, elevated status, and ranks of perfection that the Shi‘a mention for these personalities in accordance with reliable verses and traditions – for example they consider them the authority (hujjat) , Imams, rulers ( wali al-amr ), and possessed of miracles – in no way have even the scent of exaggeration or polytheism. All of them represent the their perfection, apex of servitude, and degree of submission to the commandments of Allah.
