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.

حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، عَنْ رَسُولِ اللَّهِ ﷺ بِقِصَّةِ الْعَبْدِ وَعَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنِ النَّبِيِّ ﷺ بِقِصَّةِ النَّخْلِ . قَالَ أَبُو دَاوُدَ وَاخْتَلَفَ الزُّهْرِيُّ وَنَافِعٌ فِي أَرْبَعَةِ أَحَادِيثَ هَذَا أَحَدُهَا .
