Assalamu alaikkum usthad While i was praying with an imam. At the last rakah. imam moved from 1st sujud to sitting position and then he moved to 2nd sujud. then only i moved to sitting position. And then i joined imam in 2nd sujud. Was my prayer correct?i Should i make up the prayer.?

Your prayer is valid, insha'Allah. This seems like waswasa to me, so do not get caught in these compulsive thoughts. This should be a lesson for you: you must follow the Imam instantly and not delay.
