It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) forbade the gharar sale (buying and selling based on deception and uncertainty).
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Harith except Asim, and Abu Musa is alone in narrating it."
