Kriyas Shema and Tefilla
1. The MB in siman 67 sk 3 paskens that besides the obligation to recite Shma there is also a chiyuv to remember Yetzias Mitzrayim which applies specifically after Nacht.
How do people, who daven Mincha followed immediately by Mariv (as was the minhag in countless kehilos throughout Europe for centuries) fulfill this obligation?
(It is evident from the MB that one does NOT fulfill this obligation by saying Vayiomer, see siman 67 sk 3 and also Tehillo le`Dovid end of Siman 58)
2. The Chadorim here in UK (and I assume in many other countries too) daven Shacharis with the boys. Which shittah do we follow? It seems that we do not go with R`T (Siman 70 seif 2) although it is ro`uy and nochon to do so, as we are often well past sof zman. So what are we doing exactly?
3. Re piyuitim. It would appear that even the Remo considers it a `kulloh` (siman 68) to say them mid Davening. Is there any point saying them after davening? Although it is said that some Gedoilim did, it is not brought down le`halocho. What is the Rov`s opinion on this?
1 One certainly fulfills their obligation with Vayomer as with any other form of mention of Yetzias Metzrayim, as quoted by the Mishan Brura 67:3 and at the end of siman 58. This is taken from the Gemara Brachos 21a, see the Shita Mekubetztes there.
2 It would seem that since for their normal functioning and for chinuch in tefilla they are only able to say Krias Shma then, perhaps they are not considered “higiah lchinuch” yet, even according to Rabeinu Tam. Some are machmir to have their son be yotzei Krias Shma before leaving the home in the morning. The Rav shlit”a has ruled that saying the first passuk is sufficient in this regard, as per the Tur Siman 46.
3 As with all minhagei Tefilla one should follow their family/community/shul’s custom.
