My talis knocked another guys teffilan wrapped up on the floor is it a bad sign
According to some opinions you should give a little bit of money to tzedakah. It is surely less than when teffilin without wrapping falls on the floor. It is not clear to me if it because of a bad sign, or as a form of teshuva because it caused something unrespectable to the teffilin.
