Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) forbade that the milk of people's animals be milked without the permission of their owners. He said: Does anyone like that someone comes to his storehouse, breaks its door, and takes out grain from it? The udders of these animals are people's food. I should not find anyone who has milked the milk of another's animal without that person's permission.
