It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever has become bankrupt, and goods are found with him exactly as they were, without his having changed anything in them, then that property belongs to the original owner who sold it." [Narrated by Muslim]
