The prohibition of Muhaqalah and Muzabanah and Mukhabarah: and selling produce before its goodness appears, and Mu'awamah: which is selling years in advance Sahih Muslim 1536 g
Translation
Jabir b. Abdullah (Allah be pleased with them) reported Allah's Messenger (ﷺ) forbidding Muzabana and Muhaqala, and Mukhabara, and the sale of fruits until they are ripe. I (the narrator) said to Sa'id (the other narrator)
What does ripening imply? He said: It meant that they become red or become yellow and are fit for eating.
