Q. Some questions concerning Asarah Beteveth on Friday this year;
We usually have trouble gathering the mincha minyan on time erev Shabbat. If we are late and after the shkiah can we still say anenu? How about reading vaichal and maftir?

A. D’var Yehoshua (63: 2) opines that if you can daven Mincha after the shkiah you can also read Vaychal and say maftir. Nonetheless, on the onset one should be careful not to recite aneynu on Shabbos, since it is improper to mention on Shabbos “on the day of our fasting”.

However, Shulchan Aruch (O.H. 289: 6) rules that if you fast on Shabbos a permitted bad-dream fast, you are to recite aneynu after the end of shmoneh esrey, before Elokay netzor (Mishnah Berurah ibid. 22)

Horav Shlomo Miller’s Shlit”a opinion is that only during the fifteen minutes after the shkiah you may finish the maftir and do an abbreviated (hoicher) sh’mone esreh including aneynu at shomeah tefilah. (See also Maharam Shik O.H. 91, in regards to the permissibility of praying Mincha after the shkiah)
