Mehfil-e-Quran..

Re: Mehfil-e-Quran..

When Imam recites quran in Namaz, when mufassir recites it while teaching tafseer, when teacher recites (and students repeat) in a Quran class, is it biddah? Are those not Mehfils?

if you recite quran in a room, and I am in another room reciting Quran, is that OK?

if we remove the wall from between those rooms, would than become biddah then?
