Selling the fruit of date palms before the signs of ripeness appear, for the sake of labor

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: It has become very common recently to sell the fruit of date palms to certain laborers before or at the beginning of the palms bearing fruit for them. The reason is that there is no one to perform the heavy work they do. He asks: Is such a sale permissible?

Answer:
It is not permissible unless he sells the date palm itself, the root of the palm; if he sells that, the fruit is included as a consequence. But if the sale is for the fruit only, it is not permissible until the signs of ripeness appear. Yes, if he buys the tree, its fruit is included as a consequence. Yes.
