A shailoh on a chicken was once brought to the Kaliver Rebbe. He told his student, Rav Shaul, the son of the Chozeh of Lublin zy’a, ‘Look into this shailoh. The man who brought the chicken is very poor and needs it for Shabbos.’
Rav Shaul picked up the chicken and, without any inspection, said, ‘It is kosher.’
The Rebbe asked him, ‘How can you say it is kosher without inspecting it?’
He replied, ‘From the Rebbe’s words, I was certain that it must be kosher.’
The Rebbe said, ‘You are correct. You ruled correctly!’
He then related that a renowned tzadik, who also had a very pleasant voice, once was nifter. When he ascended to the World of Truth, they honored him with serving as chazan for Kabalas Shabbos. However, a woman stepped forward holding a chicken and said, ‘I once brought a shailoh on this chicken to this Rov and he did not want to spend time to find a leniency. He ruled that it is treif and I had no meat for Shabbos. If he had taken the time, he could have found a heter.’
The Heavenly Court ruled that since he denied a woman of her joy on Shabbos, he could not serve as the chazan for Kabalas Shabbos.
‘Therefore,’ the Rebbe said, ‘it was good that you ruled that the chicken is kosher.’
