السلام عليكم ورحمة الله وبركاته Is praying behind a barelvi imam impermissible even if you have no proof of his kufr? (I thought it is allowed based on what Shaykh Ibn Taymiyyah said). You said that you can't pray behind someone who prostrates to graves. But do we assume all barelvis do this?

Ustadh AbdulAziz al-Haqqan

I can't assume this as i am not fully aware of their beliefs.
