After Fard in my country, people raise their hands and do collective Dua, I don’t participate as it is a Bid’ah. Should I leave as I don’t want Allah’s anger and punishment to descend upon me as I am present there? Or can I sit there as per the Hadith that the angels keep making dua for me?

Ustadh AbdulAziz al-Haqqan

You can make the sunnah by making your athkar and standing up going somewhere else if you want and i u do your athkar and pray the sunnah if you won't pray it at home.
