Water left over by animals

Q 3: Is it permissible to perform Wudu' (ablution) with drinking water left over by animals, such as cows, buffalos, goats, sheep, and donkeys, even if this water is placed in a container?

A: The drinking water left over by any of the animals that are lawful to eat is Tahir (ritually pure), because the Prophet (peace be upon him) ordered a person sick with fever to drink the urine and milk of camels.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
