bukhari:2203Abū ʿAbdullāh > Lī Ibrāhīm > Hishām > Ibn Jurayj > Ibn Abū Mulaykah Yukhbir > Nāfiʿ a freed slave of Ibn ʿUmar

If pollinated date-palms are sold and nothing is mentioned (in the contract) about their fruits, the fruits will go to the person who has pollinated them, and so will be the case with the slave and the cultivator. Nafi' mentioned those three things.  

البخاري:٢٢٠٣قَالَ أَبُو عَبْدِ اللَّهِ وَقَالَ لِي إِبْرَاهِيمُ أَخْبَرَنَا هِشَامٌ أَخْبَرَنَا ابْنُ جُرَيْجٍ قَالَ سَمِعْتُ ابْنَ أَبِي مُلَيْكَةَ يُخْبِرُ عَنْ نَافِعٍ مَوْلَى ابْنِ عُمَرَ

أَنَّ أَيُّمَا نَخْلٍ بِيعَتْ قَدْ أُبِّرَتْ لَمْ يُذْكَرِ الثَّمَرُ فَالثَّمَرُ لِلَّذِي أَبَّرَهَا وَكَذَلِكَ الْعَبْدُ وَالْحَرْثُ سَمَّى لَهُ نَافِعٌ هَؤُلاَءِ الثَّلاَثَ
