According to the sounder of the two scholarly views, it is permissible to sell produce that is harvested time and again—such as clover, leafy greens, cucumbers, and eggplants. One may therefore sell both the present and the forthcoming pickings and cuttings.
Shaykh al-Islam Ibn Taymiyyah (may Allah have mercy on him) said: “The correct view is that these items do not fall under the Prophet’s ﷺ prohibition. A contract is valid for the produce that already exists as well as that which has yet to appear, until the cucumber bed dries up, for people have a genuine need for such transactions. Hence it is permissible to sell vegetable beds without their roots.”
The eminent scholar Ibn al-Qayyim (may Allah have mercy on him) added: “He only forbade the sale of fruit that can simply be left until its ripeness becomes evident; vegetable beds are therefore outside the scope of that prohibition.”
