Chapter 30
General Rules Relating to Actions Performed by a Non-Jew on Shabbath and Yom Tov
APPLICABLE PROHIBITIONS
7.c. 1) When there is no light whatsoever in the room, there is a prohibition against benefiting from a light turned on by a non-Jew.
2) There is a prohibition even if the non-Jew turned on the light for a Jew of his own volition, without receiving any hint to do so.
3) For the extent to which the circumstances affect the prohibition see paragraphs 37 and 38 below.
4) Benefit derived from the turning on of a light by a non-Jew where previously there was no light what-soever is both direct and substantive, since, with-out any light, one could not see at all.
5) This type of benefit is not allowed, even where a mitzva is concerned, as where the switching on of the light enables one to study Torah or to pray.
8.a. One may say to a non-Jew on Shabbath, “I have no fearing toilet paper,” so that he realizes himself that one wishes him to tear sheets off the roll.
8.b. Here again he is merely being told a fact from which he can deduce the necessity for the performance of the forbidden act.
