The following story was shared by Rav Aviner in response to a halachic query about using electric shavers…
There is a story about a Holocaust survivor who knew the Satmar Rebbe before the Holocaust and came to visit the him in America. The Rebbe’s students saw a clean-shaven Jew speaking about all sorts of Torah subjects with the Rebbe and were surprised.
After he left, one of the students asked the Rebbe: who is this clean-shaven person who came to speak with the Rebbe?
The Satmar Rebbe responded: "When that Jew ascends to give a divine accounting, Hashem will ask him: "Jew, where is your beard?" But when you ascend to give a divine accounting, Hashem will ask you: "Beard, where is your Jew?"
