Anas b. Malik (Allah be pleased with him) reported that Allah's Messenger (ﷺ) forbade the sale of fruits until these are mellow. They (the companions of Anas) said
What is meant by" mellow"? He said: It implies that these became red. He said: When Allah hinders the growth of fruits, (then) what for the wealth of your brother would become permissible for you?
