Sayyiduna Hakim bin Hizam (may Allah be pleased with him) narrates: I submitted, "O Messenger of Allah (peace and blessings of Allah be upon him), I am a person who buys goods, so what part of it is lawful for me and what part is unlawful for me?" The Prophet (peace and blessings of Allah be upon him) said, "O my nephew! When you buy something, do not sell it further until you have taken possession of it." (Imam Ibn Hibban, may Allah have mercy on him, says:) This narration is famous as being transmitted from Sayyiduna Hakim bin Hizam (may Allah be pleased with him) through Yusuf bin Malik. In this, there is no mention of the narrator named Abdullah bin Ismah, and this narration is "gharib" (rare/isolated).
