In 1856, Rabbi Avraham Yaakov Friedman of Sadugura, was arrested because of a libel and was kept in prison.
“I am permitted to serve the Almighty undisturbed,” Rabbi Avraham Yaakov told his visitors, “What difference does it make whether I am here, or anywhere else?”
His father in law, Rabbi Aharon Perlow of Karlin, who was allowed to stay with him for a while in his cell, asked him, “How do you feel in this awful place?”
Rabbi Avraham Yaakov replied, “Does the place one is in make a difference? The Almighty’s glory fills the earth. He is everywhere. Even here, in this awful place.”
