Q. Re- question 3157 above on women not touching a Sefer Torah during their period. Can they touch it with a Siddur, as I have seen done in some synagogues?
A. Horav Shlomo Miller’s Shlit’a opinion is that it is improper to use a Sefer for this purpose.
Although, one uses usually the Tzitzis to kiss the Torah, they are only a ‘Chefetz Shel Mitzva’ or an utensil used and dedicated for mitzva purposes, while a Siddur is a ‘Chefetz Shel Kedusha,’ or a utensil that has holiness and therefore is subject to more restrictions.
