Reply To: Chidushim on Daf Yomi

If the time ran out for mincha and he forgot yaleh veyavo but at night it is not Rosh Chodash anymore
should he daven two shmonei esreis? The Tur 422, brings an argument. The Ri holds why say it with no benefit, but the Chachmei Province say that, if yaleh vayavo is left out, it is not considered davening. The Rosh rules that he should daven betoras nedava and nothing new needs to be added, because the davening itself is out of the ordinary.
