All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
We have no knowledge about the ideology of this group. Anyway, it is incumbent upon every Muslim to follow the guidance of the Prophet and his companions in words and action. Allaah says (interpretation of meaning): {And if you obey him, you will be [rightly] guided.}[24:54]. Allaah further says (interpretation of meaning): {And whoever contradicts and opposes the Messenger after the right path has been shown to him, and follows other than the believers' way, We shall keep him in the path he has chosen, and burn him in Hell- what an evil destination.}[4:115]. So one has to be very careful of any way or methodology that contradicts the guidance of the Prophet even if their advocates affiliate themselves to the family of the Prophet . What counts is the reality of the matters not its names or titles. In our contemporary life, it is predominant that the groups that claim to follow such methodologies are innovators in religion. It is confirmed that the Prophet addressing his companions said: "Those of you who live after me will see great disagreement. Thus you must adhere to my Sunnah and the way of the rightly-guided Caliphs. Hold to it and stick fast to it. Avoid newly invented matters, for every newly invented matters is an innovation, and every innovation is a misguidance." [Abu Daawood].
Finally, we advise you to consult one of the Islamic foundations that are upon the methodology of Ahlus-Sunnah Wal-Jamaa'h, to find out about the basis of the methodology of this group.
Allaah knows best.
