Reading behind a barelvi Imam?

In the name of Allah, the most Beneficent, the most Merciful.

Answer

If the Imam holds such beliefs, which negate Imaan, such as believing the Prophet of Allah Sallallahu Alahi Wasalam to be Haazir and Naazir and Alimul Ghaib, then it will not be permissible to read behind him, otherwise it will be correct. (Fatawa Haqqaniyah p.171 v.1)
