Is it bidat to make dua in congregation regularly after fard prayer?
Answer:
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Making Duā collectively after obligatory prayers is permissible on condition that one does not believe this to be necessary or mandatory. [1] It must be ensured that the audible Duā does not cause disturbance to those who are completing their missed prayers. [2]
