A Yid from Tzfas relates: There was a strange, very unpleasant smell in our kitchen. I searched for the source of it and found nothing. Knowing that Hashem does everything, I davened to the Creator of all sorts of besamim to send me a yeshuah, and I gave tzedakah. Afterward, I called a plumber and he told me, “There is probably a certain type of pipe you have there. Switch it, and the smell will pass.”
I did as he said and the smell disappeared, but several days later it came back.
I davened to Hashem to help me, and immediately afterward I had the idea to call a professional whom I hadn’t thought of previously. He heard about the problem and told me, “Before I come and take money from you, try to see what happens after the water in the sink runs for several minutes.”
I opened the faucet. Soon clean water flowed through the pipe, and the smell passed, never to return.
Thank you, Hashem, Who hears our prayers.
