Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "A pledged animal may be milked and may also be ridden." The narrator said: I told this to Ibrahim, and he regarded deriving benefit from a pledged animal as disliked.
