Q. Someone took off his tefilin on Rosh Chodesh before Musaf in a hurry and placed them without their cover on a slanted shtender next to him. Then someone else walked by and not expecting that tefilin would be placed there and like that, by accident his talis hooked on them and they fell on the floor. Who is liable to fast?
A. Horav Shlomo Miller's Shlit'a opinion is that the one who actually caused the tefilin to fall is more responsible and should therefore fast. while the one who placed them there, can redeem his fast by donating for tzedaka,
