1,369. A Baal Korei in Mourning
219:3 If the person who is paid by a shul to read the Torah becomes a mourner, he should not go to that shul on the Shabbos of shiva. This is because, if he is there, it is doubtful whether or not he should read the Torah
219:4 Shabbos counts towards the seven days of shiva. This is true even if he received timely news on Shabbos, when one does not yet begin to observe the mourning practices, and he tears his clothes after Shabbos ends.
