One Shabbos, a fire broke out in the vacant home of Yosef ben Simai, the Roman emperor's treasurer. A squad of soldiers was promptly dispatched to put out the flames, but because of his respect for Shabbos, Yosef did not let them act, though they were acting of their own accord. Immediately, rain began to pour, and the fire was extinguished. After Shabbos, he sent the soldiers recompense for their efforts.

Without forewarning, one of the wealthy Yidden residing in Yerushalayim began rapidly losing his riches, until he reached a point of dire straits. One of his acquaintances went to Reb Shlomo'le of Zvil to ask for a yeshuah. Said the tzaddik, “Had this man not thought about his business matters on Shabbos and Yom Tov he would not have lost his possessions.”
When the former wealthy Yid heard what the tzaddik had said, he admitted, “The Rebbe is correct. I used to do business with Arabic dealers on Motzoei Shabbos and Yom Tov, and would therefore plan these transactions during the afternoon hours on the holy days.”
From then on, the Yid stopped faring as such, and his financial situation improved.

When the Frierdiker Rebbe was imprisoned in Shpalerke, he received his Shabbos clothing, which were sent from his home, on Erev Shabbos. After dressing himself, the Rebbe checked the pockets as he one should on every Erev Shabbos, to ensure that he would not carry outdoors. In his pants pockets he found a slip of paper which he had received on the Motzoei Shabbos prior to his imprisonment. The paper contained information that could harm him were it to reach the hands of the investigators. The Rebbe immediately destroyed it and was thus saved.
