Ahsanallahu ilaikum, the imam in the masjid said "madad ya abdul qadir jilani" before staring the khutba but it was the first time and the imam seems to be ignorant on this matter. Rest of the time he makes dua to Allah. Can we pray behind such imam and how can I advise him? JazakAllahu khairan

Ustadh AbdulAziz al-Haqqan

I would pray behind someone else, and if it is wise to advise him then do so, or bring someone knowledgeable to advise him.
