A good Yid from Yerushalayim wanted to be machmir with the halachos of Shabbos, so he installed a Shabbos electric generator on the roof of his building. A neighbor of the building was jealous of him and slandered him to the authorities. He went to the tax authorities and tipped them off that this neighbor engages in tax evasion. His proof was that this neighbor traveled a lot to America and to other countries. That means that he must be an international businessman, and he doesn't report his earnings to the government. (In reality, he was a fundraiser for a kollel, and he travelled often for that purpose.)
The authorities arrived at the neighbor's home to investigate. Of course, they found nothing at all. But one thing they did discover. The wife's name was מאשה, and not משה, as they had initially written in their books. Until now, they thought מאשה was a man; now they discovered that she is a woman. In Eretz Yisrael, men pay more taxes than women do, so this correction saved them money. The man who spoke against them to the police thought he was harming them, but he was actually helping them. Their taxes will now be less, and they were also refunded for all the years they were overcharged. The lesson is that everything is from Hashem, and even those matters that seem to be bad, at first, are for our good.
