Q: I heard that using a tasbeeh is bid'ah, is this true?

Q: I just want to know if loud zikr in a congregation is permissible because some say it is and some say it's bida. Please give me an explanation. Didn't our beloved prophet (Sallallahu Alayhi Wasallam) or those around him practice this kind of zikr?
