Sunan Abi Dawud 1592

Explaining the meaning of Jalab and janab Muhammad bin Ishaq said The meaning of jalab said is that the zakat of animals should be collected at their places (dwellings), and they (animals) should not be pulled to the collector of zakat. The meaning of janab is that the animals are removed at a distance (from the collector). The owners of the animals should do so. The collector of zakat should not stay at a distance from the places of the people who bring their animals to him. The zakat should be collected in its place.
