It is narrated from Ma'mar bin al-Muthanna that: Sa'sa'ah bin Mu'awiyah bin Husayn bin Umayr bin Ubadah bin al-Nazzal bin Murrah bin Ubayd bin Muqa'is bin Amr bin Ka'b bin Sa'd bin Zayd Manat bin Tamim; he is the paternal uncle of Sayyiduna al-Ahnaf bin Qays (may Allah be pleased with him).

It is narrated from Sayyiduna Sa'sa'ah bin Mu'awiyah (may Allah be pleased with him) that I came to the Prophet (peace and blessings be upon him) and heard him (peace and blessings be upon him) reciting this verse: "So whoever does an atom's weight of good will see it, and whoever does an atom's weight of evil will see it." [Surah al-Zalzalah: 7-8] I said: I do not care to hear anything besides this; it is enough for me, it is enough for me.
