If someone sells pollinated date palms, their fruits will be for the seller, unless the buyer stipulates the contrary

Do you think I bargained with you to take your camel? Take your camel and your dirhams; these are yours
Jābir ibn ‘Abdullāh (may Allah be pleased with him) reported: I was traveling on a camel and it got exhausted, and I decided to release it. However, the Prophet (may Allah's peace and blessings be upon him) caught up with me, supplicated for me, and struck it. Thereupon, it started to walk like never before. Then, he said: "Sell it to me for an ounce." I said: ‘No.’ He again said: "Sell it to me." So, I sold it to him for an ounce, but made the stipulation that I should be allowed to ride it back to my family. Then, when I reached home, I took the camel to him and he paid me its price on the spot. As I went back, he sent someone after me and said: "Do you think I bargained with you to take your camel? Take your camel and your dirhams; these are yours."
