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).
