Is it permissible to pray behind a group called (the Barelvis)? Are they among the Sufis? And what is the proof of that?

The Barelwi movement is a Sufi sect that originated in India, founded by Ahmed Raza Khan. They are known for their exaggeration regarding prophets and saints. Among their false beliefs are: that the Prophet, peace be upon him, is an absolute deputy of Allah and disposes of the universe, and that saints have the ability to dispose of it. They elevate the Prophet to the status of divinity, believing that he is present and observes the actions of creation, and they deny his humanity. They encourage seeking help from prophets and saints, and they advocate for the practice of "Isqat" (redemption) as a charity paid on behalf of the deceased for missed prayers and fasting. These beliefs are infidelic, and whoever believes in them exits the fold of Islam. It is not permissible to pray behind such a person.
