Narrated by Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever believes in Allah and the Last Day, it is not lawful for him to untie the teat of a she-camel without the permission of its owners, because this is like a seal on the animal's milk. And when you are in a deserted place and you find a full water-skin of milk there, then call out to the camel owners three times; if its owner gives you permission to drink, then drink, otherwise do not. And if you are in need and do not have food with you, then two of you should hold it and then you may drink.
