We do not recite the blessings over the flame or over the fragrant spices of idolaters, nor over the flame or fragrant spices of the dead, nor over the flame or fragrant spices [placed] before an idol. We do not recite the blessing over the flame until benefit is derived from its light.

Beis Shammai say: [The blessing over] the flame [is first, followed by] Bircas HaMazon, [the blessing over] fragrant spices, and [then] Havdalah. But Beis Hillel say: [The blessing over] the flame [is first, followed by the blessing over] fragrant spices, Bircas HaMazon, and [then] Havdalah. Beis Shammai say: [The blessing is worded] ‘‘. . . Who created the illumination of fire.’’ But Beis Hillel say: [It is worded] ‘‘. . . Who creates the illuminations of fire.’’
