Thabit al-Bunani (may Allah have mercy on him) relates that he heard Sayyiduna Abu Hurayrah (may Allah be pleased with him) say that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, the Ansar are my special confidants with whom I took refuge. So accept (the good) from those of them who do good, and overlook those of them who do wrong, for they have fulfilled the duty that was upon them, and what remains is the right that is theirs (upon you)."
No one narrated this hadith from Thabit al-Bunani (may Allah have mercy on him) except Ma'mar (may Allah have mercy on him).
