It’s time for that special Friday Minchah again:
If one forgets to say ya’aleh v’yavo at Minchah Friday Rosh Chodesh, and doesn’t remember to repeat shemoneh essrei before it is already too late, and Shabbos is NOT Rosh Chodesh, it is a major shayloh if one can daven ma’ariv twice. Such a case (where you will not be saying yaaleh veyavo at the make-up tefillah) is a general shayloh even if it occurs during weekdays, and the aytzah given is to daven the “repeat” Tefilla as a nedava – but this cannot be done on Shabbos!
Mishnah B’rurah says: Only one shemoneh essrei by Ma’ariv. No aytzah, sorry.
Aruch HaShulchan is noteh: Two amidahs by ma’ariv– the Halacha is to treat the Minchah simply as a missed Tefillah, and it doesn’t matter if you will not be saying ya’aleh v’yavo at the makeup Tefillah.
Rav Malinowitz says: DON’T FORGET YA’ALEH V’YAVO AT MINCHA!! (and if you do, remember that you forgot before sheki’ah – or before you are mekabel Shabbos – and daven Minchah again.)
