Q. I follow avidly the Shailes that you post on Frum Toronto and the well documented answers you provide. I also greatly appreciate the very learned opinion of a Gadol Hador as Horav Miller shlita.
I have a number of questions that came up on the shailes of the last weeks.
On taking off the talis before the tefilin (question 490), is there an isur in doing so?

A. Alivo Dechilcheso (y. 5768, pub. 17) quoting Horav Chaim Kanievsky Shlit’a (Doleh Umashke) mentions that if someone did remove his taalis before the tefilin, no actual prohibition was done. Horav Shlomo Miller Shlit’a agrees in that it is not a prohibition but nonetheless a halocho to be followed.

On the haskomo witten by Horav B. Siver Shlit’a to Nesivos Hachalocho, he mentions that the ones who have difficulty wearing a taalis in a hot day but want to continue learning after davening with the tefilin on, can rely on the fact that they are still wearing a taalis kotton.
