Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever finds his property intact with a bankrupt person, he has more right to take it than anyone else."
Whoever sells his property to someone, or deposits it with him, or loans it to him or the like, and then that person (who received it) becomes bankrupt or insolvent, meaning that his money is not enough to pay off his debts, then the seller has the right to take back his property if he finds it as it is, as he is more entitled to it than any other person.
