This tradition has also been narrated by Umar from the Messenger of Allah ﷺ through a different chain of narrators. It mentions only the sale of the slave. It has also been transmitted by Nafi on the authority of Ibn Umar from the Prophet ﷺ indicating only the sale of palm-trees. Abu Dawud said: Al-Zuhri and Nafi differed among themselves in four traditions. This is one of them.
