Allah's Messenger (ﷺ) forbade the selling of fruits until they were ripe. The Prophet (p.b.u.h) added, "It means that they become red ."
Sahih al-Bukhari Book 24, Hadith 88
← Previous Hadith The Prophet (ﷺ) had forbidden the sale of fruits till they were ripe (free from blight).

Sahih al-Bukhari Book 24, Hadith 87 Next Hadith → `Umar bin Al-Khattab gave a horse in charity in Allah's Cause and later he saw it being sold in the market and intended to purchase it. Then he went to the Prophet (ﷺ) and asked his permission. The Prophet said, "Do not take back what you have given in charity." For this reason, Ibn `Umar never purchased the things which he had given in charity, and in case he had purchased something (unknowingly) he would give it in charity again.
