Can one say one’s congregational prayer behind a Sunni Imam with the intention of Jama'at (congregation)? And should one recite al-hamd on his own?
Answer
it is permissible to offer prayer in their congregational prayers, in areas where Taqiyah (dissimulation) is required. However, it is obligatory upon you to recite al-Hamd and the second chapter yourself – be the recitation in low voice though.
