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.

Shu'bah states: I asked Sa'd bin Ibrahim about Banu Najiyah, and he said: "They are from us." Shu'bah states: People have narrated from Sayyiduna Sa'id bin Zayd (may Allah be pleased with him), from the Prophet (peace and blessings be upon him),
this narration: "They are a clan that is from me." The narrator says: I think the narration also contains these words: "And I am from them."
Abu Ya'la recorded it, and its narrators are the narrators of the Sahih, except that the narrator Sa'd bin Ibrahim did not hear from Sayyiduna Sa'id bin Zayd (may Allah be pleased with him).
