It is narrated from a freed slave of Musa bin Talhah, or perhaps from a son of Musa bin Talhah, from his father, from his grandfather, who said: The Prophet (peace and blessings be upon him) would perform ablution after (drinking or eating) camel's milk or meat, but he would not perform ablution after (consuming) sheep's milk or meat, and he (peace and blessings be upon him) would pray in their pens.
Imam Abu Ya'la recorded this report; its chain contains a narrator whose name has not been mentioned.
