shabbat 26

a volatile relationship between a woman and her mother-in-law that led to her incineration.

and what makes a garment that covers the body, also makes a succah covering.

(story of a woman who was instructed by her mother to wear balsam oil and then light the lamp, as an illustration of the unsuitability of balsam oil for shabbat lamps as it is too volatile. and the definition for what is a garment is a woven fabric of 3x3 finger-breaths that is able to become ritually impure. and nothing that can become ritually impure can be used to cover the succah. for english translation of this talmud page, see here)
