Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The buyer and the seller both have the option (to cancel the sale) as long as they have not separated, unless it is a sale with a stipulated option (in which case the ruling is different)." (Allamah al-Haythami says:) I say: The narration of Sayyiduna Abu Hurayrah (may Allah be pleased with him) recorded by Abu Dawud and al-Tirmidhi (has the words): "The two should part from each other only with mutual consent."
Ahmad recorded it; its chain contains Ayyub bin Utbah, whom the majority declared da'if (weak), though he has also been declared trustworthy.

Al-Tabarani recorded it in al-Mu'jam al-Kabir via Abu Mu'awiyah from Abdullah bin Qays al-Aslami; I do not know the narrator Abu Mu'awiyah, and the rest of its narrators are thiqat (trustworthy).
