Al-Qasim bin Mukhawwal al-Bahzi narrates from his father that he said: O Messenger of Allah! We come across camels (on the way) whose udders are tied (to hold back the milk) and are full of milk (musarrah), while we are in need (so what should we do)? He (peace and blessings be upon him) said: "Call the owner of the camels three times; if he comes, (well and good,) otherwise milk it and drink, and untie the knot (of the udders); then (after drinking) tie it again and leave some milk in the udders (for the young, or so that it may gather again)."
