The Kaliver Rebbe once spent Shabbos in a certain village. During Kabalas Shabbos, people began to scream that a fire had broken out in the silo of his host. The host wanted to run to save his grain, but the Rebbe grabbed his hand and said, "Stay here. I want to tell you a story."
He related, "The Rebbe Rav Zushe zy’a was once saying Tehillim with much enthusiasm before Kabalas Shabbos. He suddenly heard people screaming that his house was on fire. They yelled, ‘Zushe, it is burning!’ He did not respond and he kept saying Tehillim. After the people yelled at him a few more times, he said, ‘So what if it is burning? It is stated: ‘Vatishkah ha’eish.’ And the fire will subside.’"
As soon as the Kaliver Rebbe said these words, they could see that the fire had extinguished itself.
