What did the Prophet Muhammad (peace be upon him) say about the ownership of the fruits in the case of pollinated date-palms being sold without any mention of their fruits?
 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.
