Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates: Once I saw the Prophet (peace and blessings be upon him) become angry over the matter of Banu Ka'b, and so intensely angry that I had not seen him so angry for a long time. The Prophet (peace and blessings be upon him) said: "May Allah Almighty not help me if I do not help Banu Ka'b." Sayyidah Aishah (may Allah be pleased with her) narrates: The Prophet (peace and blessings be upon him) said to me: "Tell Abu Bakr and Umar to prepare for this campaign." The narrator says: Those two men came to Sayyidah Aishah (may Allah be pleased with her) and said: "Where does the Prophet (peace and blessings be upon him) intend to go?" Sayyidah Aishah (may Allah be pleased with her) replied: "I have seen the Prophet (peace and blessings be upon him) so angry over the matter of Banu Ka'b that I have not seen him so angry for a long time."
Abu Ya'la recorded it from Hizam bin Hisham bin Hubaysh, from his father, from Sayyidah Aishah (may Allah be pleased with her). Ibn Hibban declared both of them thiqah (trustworthy). The remaining narrators of this report are the narrators of the Sahih.
