The Messenger of Allah (ﷺ) prohibited Muhaqalah and Muzabanah.

There are narrations on this topic from Ibn 'Umar, Ibn 'Abbas, Zaid bin Thabit, Sa'd, Jabir, Rafi' bin Khadij, and Abu Sa'eed.

The Hadith of Abu Hurairah is a Hasan Sahih Hadith.

Muhaqalah is selling corps for wheat, and Muzabanah is selling dates that are on the date-palm for dried dates. This is acted upon according to the most of the people of knowledge, they disliked sales of Muhaqalah and Muzabanah.
Jami` at-Tirmidhi Book 14, Hadith 23
← Previous Hadith That the Messenger of Allah (ﷺ) said: "The dweller of the town is not to sell for the Bedouin, leave the people ; Allah provides for some of them through others."

The Hadith of Abu Hurairah is a Hasan Sahih Hadith, and this Hadith of Jabir is a Hasan Sahih Hadith as well.

This Hadith is acted upon according to some of the people of knowledge among the Companions of the Prophet (ﷺ) and others. They dislike the dweller of the town to sell for the Bedouin, while some of them permitted the town dweller to purchase for the Bedouin. Ash-Shafi'i said: "It is disliked for the dweller of the town to sell for the Bedouin, and if he does sell, then the sale is permissible.

Jami` at-Tirmidhi Book 14, Hadith 22 Next Hadith → "Zaid, Abu Ayyash asked Sa'd regarding white wheat in exchange for barley: which of them was better ? He said the white, then he forbade that. Sa'd said: 'I heard the Messenger of Allah (ﷺ) being asked about selling dried dates for ripe dates and he said to those present: "Will the fresh dates shrink when they are dry ?" They said yes, so he forbade that.'"
