Is there a source that one shouldn’t check the deceased Tefillin after they have died?
1 Answer
The poskim - see for instance Rambam Hilchos Tefillin 2(11) - bring a source (Yerushalmi last perek of Eiruvin - Kesef Mishnah) that Hillel (some say Shammai) used his grandfather's tefillin without needing to check them. That is part of a discussion there whether tefillin need checking in general, or how often. I don't know that it had anything to do with his grandfather dying, just that tefillin, wrapped securely in their batim, don't need frequent checking - others argue.
