I see a ???? ?????? in the Mishna Berurah (???? ??”?, ?”? ?”?) that it is not permitted to learn during ???? ??”?. I constantly notice chashuvah men and numerous Yeshiva Bochurim reading from a sefer during it. Does anyone out there know of a heter? If not, how would you handle it?
What makes them “chashuv”? They are sinners.
Ben Olam Haba of Lakewood writes:
The Shulchan Aruch HaRav Siman 124:6 writes that people who learn or say other Tachanunim (such as tehilim) during Chazaras HaShatz should be chastised for doing so as what they are doing is not proper. (!)
See also Igros Moshe Orach Chaim Vol. 4 Siman 19 that this is all the more so when actually in a small minyan where there may not be 9 people answering Amen.
