It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) forbade the sale and purchase of fruit before it ripens. The people asked: O Messenger of Allah! What is meant by the fruit ripening? The Prophet (peace and blessings be upon him) said: "When the risk of spoilage is gone from it and the good fruit becomes distinct."
