A widow whose kesubah was two hundred [zuz], and who sold [property] worth a hundred for two hundred, or [property] worth two hundred for a hundred —- has received her kesubah.  [If] her kesubah was a hundred, and she sold [property] worth a hundred and a dinar for a hundred, her sale is void. Even if she says: “I will return a dinar to the heirs,” her sale is void. Rabban Shimon ben Gamliel says: Her sale is always valid, unless there would be enough for her to leave over —- in a field, an area of nine kavin; in a garden, an area of half a kav, and —- according to R’ Akiva’s view —- an area of a quarter [of a kav].  [If] her kesubah was four hundred zuz, and she sold to this one for a hundred, and to this one for a hundred, and to the last one, [property] worth a hundred and a dinar for a hundred, [the sale] of the last one is void, but the sales of all the others are valid.
