Anas (RA) reported that Allah's Apostle (ﷺ) forbade the sale of the fruit of date-palms until it becomes mellow. We (some of the other narrators in the chain of transmitters) said: What does the word" mellow" mean? He said: (There the fruit) turns red or yellow. Don't you see if Allah had checked (the growth of) fruits; then what for the wealth of your brother would be permissible for you?
Anas bin Malik (RA) 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?
Anas (RA) reported Allah's Apostle (ﷺ) as saying: If Allah does not fructify them, then what is permissible for one of you to take the wealth of his brother?
