Is the sale of the roots of recurring-fruiting vegetables permissible without stipulating immediate harvesting?

Primary text

The sale of the roots of these recurring-fruiting vegetables (like cucumbers and gourds) is valid without stipulating the cutting of the fruit. This is the doctrine of Abu Hanifa and Al-Shafi'i. There is no distinction based on whether the roots are small or large, or whether they are currently bearing fruit or not, because they are roots that yield recurring fruit, thus resembling trees.
