Narrated by:Nafi'
Narrated Nafi', the freed slave of Ibn 'Umar: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.
قَالَ 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.
