"It turns red or turns yellow." Recorded by al-Bukhari (6). And he forbade the sale of grapes until they turn black. Recorded by al-Tirmidhi and Ibn Majah (7). The hadiths regarding this are numerous, all of which point to this meaning.

If it is after its suitability has appeared (2), it is permissible absolutely, as well as on the condition of harvesting or leaving it, according to what we mentioned regarding the fruit of trees.
