Related על סוכה 3:13

On the first day of the festival no man fulfills his duty with his neighbor's lulav, except if he has given it to him as a real gift. There is a story of Rabban Gamaliel and the elders who were going on board a ship and had no lulav with them. Rabban Gamaliel bought a lulav for a gold denarius, and when he had fulfilled his duty with it, he gave it as a real gift to his fellows, and when they had in turn passed it on and fulfilled their duty they returned it to him. Rabbi Yose said, "On the first day of the festival, after one has fulfilled his duty with the lulav, he is forbidden to remove it."
