It is narrated from Hazrat Usaid (may Allah be pleased with him) that someone asked the Holy Prophet (peace and blessings be upon him) about the ruling on camel's milk. The Holy Prophet (peace and blessings be upon him) said: After drinking it, perform ablution. Then he asked about the ruling on goat's milk, so he said: After drinking it, do not perform ablution.
