Rav Moshe Shternbuch: Learning Mishnayos In An Aveil's House?
The gemara (Moed Katan 23a) says that we do not learn Torah in a Bais Aivel. The Rambam and the Shulchan Aruch pasken that way as well. If so how can there be a minhag to learn Mishnayos in an Aveil's house? This question was asked to Rav Moshe Shternbuch (4:271). In fact said the questioner, he knew of a Gadol who specifically told his children to make sure no mishnayos is learned in the house during the Shiva.
Rav Shternbuch answered that a similar problem exists with Kaddish at the Levaya which for the same reason as above, should not be said in the presence of the Niftar. The reason why Kaddish is said is because rather than embarrass the Niftar who cannot do mitzvos, it is a great Zechus for his Neshama. The same thing applies with Mishnayos, said Rav Shternbuch, the learning is for the benefit of the Niftar and therefore is not something that is forbidden.
Similarly Hespeidim and Mussar at the levaya that inspire others by reminding them how fragile life is, all goes for the Zechus of the Niftar, since through him people better themselves. U'Minhag Yisroel Torah Hu!
