לא יתענה אדם בשבת על שראה בחלום הפסד ממון אלא על מה שיכולין לחלל עליו את השבת:
Medieval Jewish mysticism, translated by Sholom Alchanan Singer. Northbrook, Ill. Whitehall Co., 1971
One should not undertake a fast on Shabbos on account of the fact that he saw financial damage in his dream except if he saw in his dream something on account of which it is permitted to desecrate Shabbos.
