Reciting Vs Listening The Quran
The Quran is constant in every scenario, its physical shape and form can vary with time. Therefore, whether one holds it and recites it, doesn’t make any difference. It is the same Quran that one is reciting. Regarding listening part in individual Salah, if a principle has been established in congregational Salah that one should listen to Qirat of Imam, which implies that listening is equivalent to reciting, then why can’t the same principle be applied to individual Salah? it is an ijtihadi application, but has a sound reasoning underneath. It is an application of principle and not an addition.
