Q. If five people already davened and five need to daven, may one of those that already davened say a tefillas nedava so that there will be six mispallelim? May this be done in a case of need, such as where they will be very hurt by not having tefilla b’tzibbur?
A. Horav Shlomo Miller’s Shlit’a opinion is that davening a voluntary Tefila, would not create a communal Tefila Betzibur. Besides, the Rov pointed out that it is not recommended to daven in our days a Tefilas Nedava, since it requires kavana and complete intention in all the brochos, and that is difficult to achieve in our times.
