And Mughira narrated, and from him Ibrahim al-Nakha'i, that: Regarding a lost animal (if someone finds it), it may be ridden in exchange for providing fodder (if it is a riding animal), and its milk may be milked according to the fodder given (if it is capable of giving milk), and likewise for a pledged (mortgaged) animal.

Narrated Abu Huraira: The Prophet said, "One can ride the mortgaged animal because of what one spends on it, and one can drink the milk of a milch animal as long as it is mortgaged. "
