Sahih al-Bukhari 2114

Ishaq told me: Habban narrated to us: Hammam narrated to us: Qatada narrated to us, from Abu al-Khalil, from Abd Allah ibn al-Harith, from Hakim ibn Hizam, may Allah be pleased with him: The Prophet, peace and blessings be upon him, said: “The buyer and seller have the option as long as they have not separated.” Hammam said: “I found in my book the wording: He chooses three times.” “If they are truthful and make matters clear, their sale will be blessed for them. If they lie and conceal, they may make a profit, but the blessing of their sale will be erased.” He also said: Hammam narrated to us: Abu al-Tayyah narrated to us that he heard Abd Allah ibn al-Harith narrate this hadith from Hakim ibn Hizam, from the Prophet, peace and blessings be upon him.
