זכור את יום השבת לקדשו (יתרו כ:ח)

A Yerushalmi merchant used to walk every Shabbos to daven Mussaf at the Kosel Hamarovi.  He used to pass the Arabic market, and the Arab vendors who dealt with him during the week would call out the prices to him as he passed.

With time, the Yerushalmi merchant’s wheel of fortune turned for the worse. His parnassah dwindled from day to day.  The merchant went to Rebbe Shlom’ke Zevilar zt’’l and bemoaned his fate, asking for a bracha.

Rebbe Shlom’ke saw with Ruach Hakodash (divine prophecy) that the Arabs share their prices during Shabbos, and he told the Yerushalmi merchant not to pass the Arab market on Shabbos, there are other routes to the Kosel – and that he will resume being successful. And so it happened.
