Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) states: the Prophet (peace and blessings be upon him) said about Banu Najiyah: "I am from them and they are from me."
Ahmad recorded it both connected (muttasil) and mursal, in abridged form; he recorded it from a nephew of Sayyiduna Sa'd (may Allah be pleased with him), but did not name him. The remaining narrators of both are the narrators of the Sahih.
