Musannaf Ibn Abi Shaybah 26978 — Reports on good character

Maymun bin Mihran said: I asked Sayyidah Umm al-Darda (may Allah be pleased with her): "Did you hear any hadith from the Prophet (peace and blessings be upon him)?" She said: "Yes! I came to the Prophet (peace and blessings be upon him) while he (peace and blessings be upon him) was sitting", or she said that he (peace and blessings be upon him) was in the mosque, or she mentioned something else. "And I heard the Messenger of Allah (peace and blessings be upon him) saying: 'The first thing to be placed on the Scale will be good character.'"
