What did the Prophet Muhammad (saw) say about purchasing pollinated date-palms and slaves with property?
 Narrated 'Abdullah (ra) said, I heard the Messenger of Allah () say "If somebody buys date-palms after they have been pollinated, the fruits will belong to the seller unless the buyer stipulates the contrary. If somebody buys a slave having some property, the property will belong to the seller unless the buyer stipulate that it should belong to him."
