AN OPINION THAT PERMITS EXTINGUISHING (Yerushalmi Halachah 3 Daf 80b)
תני אף מכבין להציל.
(a)
(Beraisa): One may extinguish in order to save [Kisvei ha'Kodesh].
מתניתא דר''ש דאמר אין דבר משום שבות עומד בפני כתבי הקודש.
(b)
The Beraisa is R. Shimon, who holds that that nothing forbidden mid'Rabanan obstructs [saving] Kisvei ha'Kodesh. (He forbids extinguishing mid'Oraisa only if it is Melachah ha'Tzerichah l'Gufah, i.e. he intends to make a wick.)
