‘Amr b. Shu'aib on his father’s authority said his grandfather reported the Prophet as saying,
“There is to be no collecting of sadaqa from a distance, nor must people who own property remove it far away,* for their sadaqat are to be received only in their dwellings.”
Abu Dawud transmitted it.
* The point is that the collector of zakat must not make people bring their animals a long distance to him, and they must not remove their animals to a distance when he is coming to collect zakat.
